Where it all began...
https://farm8.staticflickr.com/7893/...d9f958ed_c.jpgUntitled by awesome_adawson, on Flickr
Hello Squarebody Friends! I’ve officially joined your ranks with the purchase of Sweet Pea, our 1975 Chevrolet Cheyenne 20. She was born in Flint Michigan, sold on Sept 20 1975 by Brooks Biddle Chevrolet in Bothell, WA to a Mr. Posey of Port Orchard WA. She lived in Port Orchard until earlier this year where she made a quick pit stop in Tacoma. After making the purchase I drove her home to sunny northern CA by way of the coastal HWY 101. Took ownership with a scant 77,163 miles on her, and clicked over 78,000 as I hit the driveway at home.

She is mostly stock, minus the late model Chevy wheels (original 16.5”s included) , an unknown chevy steering wheel (original included) a hefty spray-in bedliner and a neat center console job put in by her long time owner. Wearing what is believed to be her original and only coat of 41 Spring Green with 12 White 2 Tone, she shines quite nicely in the sun! 350/400 and a 14 bolt are the running gear, not sure on the rear end ratio but she goes 70 on the highway without complaint. Acres of green interior, and beautiful dash and gauge cluster and a crisp am/fm radio (hooked up to janky house speakers behind the seat!) provide the creature comforts. Heater/defrost work like a charm, tilt wheel, wipers/lights etc all functioning properly. I was pumped to open up the glovebox and not only find the SPID intact, but the original owners manual, warrantee card and dealer maintenance sheets. This truck is definitely one that has been preserved.

My plans for her include:
-16”x8” steelies from wheel vintiques, powder coated white. Original hubcaps. All terrain tires, 265/75/16 or 285/75/16.
-LED lighting upgrades, tails, reverse, cargo, dome, gauge cluster.
-Speakers, want to keep the am/fm but perhaps add a Bluetooth receiver.
-Recover the seat.

So I found this truck on CL, and made a deal with the seller. I flew up to Seattle the next day and made the purchase. I took lots of fun pictures during my 3 day journey back home, and I’ll leave them here for you to check out.
5 minutes after I bought her, had to pull over to take a pic!

The first night I headed south to Portland, then west out to Tillamook where I got some much needed rest for the night. Next morning I was up and on the road early, headed south on 101.

Didn’t make it far before I had to stop and take a few pics!
https://farm8.staticflickr.com/7895/...70a1f3c6_c.jpgUntitled by awesome_adawson, on Flickr
Just outside Beaver, OR, I found this great little roadside antique/ automobilia shop, complete with cabin rentals, should you need a place to stay!

Up the road a few I stopped, for some Firearms, Groceries… and Beaver?

Made yet another pit stop in Cloverdale, OR, where I found this amazing lid. Couldn’t pass it up!

Once properly attired, I hit the road again.

Pulled off for a walk on the beach just south of Lincoln City
https://farm8.staticflickr.com/7813/...7f84df3e_c.jpgUntitled by awesome_adawson, on Flickr
Found this awesome folding camp chair/lounger combo at an antique shop. Had to have it! Screams 1975 for sure!

Had lunch at a Pizza joint that had this KILLER bench! They woudn’t sell it to me.

Spotted this outside a wrecking yard somewhere north of the Oregon Dunes

Got hassled by some locals so I kept on pushing south

Put up in Brookings for the night. Woke to heavy rain and pushed on through. It dumped like crazy from Brookings all the way home, but Sweet Pea had no trouble, being a PNW gal she’s no stranger to the wet weather.
Just outside of Legget, CA I had to stop at the great drive thru tree.

After 3 days of travel, nearly 900 miles of driving, rainstorms, landslide closed sections of hwy 101, sketchy detours through the backroads of Western Oregon, about 15 different antique shops, and countless smiles, Sweet Pea and I arrived home… Thanks for following along folks, I’ll report back often on the status…

-Cheers

Re: "Sweet Pea" 1975 Cheyenne 20
 

I have had a lot of square body trucks.
But none that nice:metal:
That's a Keeper.

Re: "Sweet Pea" 1975 Cheyenne 20
 

Sweet Pea has clearly been loved on her whole life, and I'm sure you will continue the affection! Shes a real beauty!

Re: "Sweet Pea" 1975 Cheyenne 20
 

Congrats on the new ride - that's a real nice one!

Re: "Sweet Pea" 1975 Cheyenne 20
 

Wow, very nice find. Looks like fun. I will say that I like the late model Chevy wheels on her, but then again, I'm a heretic. I'm impressed with how well all the panels line up, amazing for a truck of that age. Looking forward to the ongoing story!

Jon

Re: "Sweet Pea" 1975 Cheyenne 20
 

Sweet truck. Good plan. Retro sound will fix you up on the tunes.

Re: "Sweet Pea" 1975 Cheyenne 20
 

Beautiful truck. Love the color scheme.

Re: "Sweet Pea" 1975 Cheyenne 20
 

man that's nice! that takes me back my dad bought a blazer that color and a pickup truck the same color for my brother that year both new! I have to show them that picture for sure

Re: "Sweet Pea" 1975 Cheyenne 20
 

Awesome truck love the original colors, very nice!!!!! Can't wait to see the new rims and caps.
Now you need to purchase a travel trailer to match, one of the older sixties ones they called canned hams, then you would have Sweet Peas & Canned Ham, what a combo that would make.

Re: "Sweet Pea" 1975 Cheyenne 20
 

Nice find...what a clean truck!

Re: "Sweet Pea" 1975 Cheyenne 20
 

Thanks! Yeah I plan on hanging on to her for a while.

Thank you! yeah it looks fairly straight! I'm 50/50 on the late model wheels. When they're shined up they look super sharp, and they're in great condition, but there's something about the white steelies that I can't let go...

Thank you! So I looked into retrosound, but I'm headed down a different path. Found a Bluetooth Amp I can hide under the seat, which will run the factory radio, and power 2 6x9's in the corner, and a pair of 3.5's in the dash spot, and also be able to play music and hands-free calling from the iphone.

Thanks! yeah it is a great look.

Oh thats awesome! got any pics of the combo together?

HAHA! love that plan. Its definitely set up to tow, and a retro canned ham would be wayyyy cool! I've got the rims in the cart, just need to replenish the funds to buy em. Still on the fence about which style caps to run. I see a lot of squarebody trucks running the earlier style dog-dish caps and i really like them better, but i have a full set of the later pie plate style ready to go... decisions...

Thanks! Yeah she's a real beauty.

Re: "Sweet Pea" 1975 Cheyenne 20
 

Very very very nice! Sweeeeeeeeet P!

Re: "Sweet Pea" 1975 Cheyenne 20
 

Things are getting serious! In the process of updating all my lights to LEDs. Got tails, backups, dome, cargo and courtesy lights. Easy bulb replacements.
Used Sylvania 1157 Red LED for tails,
Sylvania 1156 6000K for reverse
GVR 1142 warm white for cargo and dome
Yitamoto 1003 for courtesy
Yorkim T10 for dash and wiper switch. DO YOURSELF A FAVOR and buy the non-polarity bulbs. That will eliminate the 50/50 chance you get with the regular bulbs upon installation.


Went to do the dash lights and it turns out its a little more tricky than I'd hoped. Had to pull the dash completely. Managed to get them all swapped out without disconnecting the speedo or oil pressure lines. Would have been easier just to do so from the beginning though. Kind of a PITA to get to all the sockets in and out.

Definitely a ton brighter! really impressed with the outcome. You do lose the dimmer function, but honestly I never really ran mine on the dimmed setting anyway. I think with the gauge bezel back on it tone down the light a tad bit. very pleased with the results. I still need 1 last bulb for the heater switch, which happened to be different than the rest of the dash bulbs. (1445 vs 168's in the dash)

Re: "Sweet Pea" 1975 Cheyenne 20
 

Just painted the cluster housing with chrome paint and installed all new 168's and it's not that bright. LED's are definitely the way to go here....looks great.

Re: "Sweet Pea" 1975 Cheyenne 20
 

stripped the interior today, and got busy cleaning up the floorboards. Some light surface rust on the pans. I sanded that off and stripped the rust with Evap-o-rust. Then shot in factory 41 Spring green from Paintscratch.

Got to work replacing the state of the art sound system that was installed in my truck...

https://farm8.staticflickr.com/7805/...6c4f99af_c.jpgUntitled by awesome_adawson, on Flickr

Bought a set of the cab corner speaker enclosures from BigBlock. Shot them in spring green and backed them with sound deadener. Kicker 6x9's.

Got the carpet underlay placed. Unfortunately I didn't order enough... :dohh:

https://farm8.staticflickr.com/7807/...27c0fb3c_c.jpg by awesome_adawson, on Flickr

Next up. Fabbing a mount for the Kicker 3.5" speakers in the dash.

https://farm8.staticflickr.com/7901/...912d0535_c.jpgUntitled by awesome_adawson, on Flickr

And need to mount this... Infinity Kappa K4 Bluetooth Amp. This will allow me to keep the stock am/fm radio, but have access to all my tunes from my phone.

https://farm8.staticflickr.com/7910/...6d7a4a4d_c.jpgUntitled by awesome_adawson, on Flickr

Time to go wire stuff up!

Re: "Sweet Pea" 1975 Cheyenne 20
 

Nice work so far. Those 6x9 brackets are sweet.

Re: "Sweet Pea" 1975 Cheyenne 20
 

Thank you! Yeah they are awesome. Click here if interested. Not a bad price either...

Re: "Sweet Pea" 1975 Cheyenne 20
 

Nice truck and upgrades. You definitely found a clean one!

Re: "Sweet Pea" 1975 Cheyenne 20
 

Little bit of an update...

Got the Amp and speakers wired up, and it sounds GREAT!!! It's super easy to use, bluetooth connects to the phone right away and plays music, even handles the phone calls! I'm pretty pumped to be honest. I love having great tunes and modern amenities, all while keeping a completely factory looking dash.

Here's the speaker mounting bracket I made. I traced the outline of the stock 4x10 speaker onto a sheet of 1/2" plastic from TAP, ($2.15 from their scrap pile) and cut it out, then used a 3 1/8" hole saw to cut out the speaker holes. I ended up using 1/2" spacers to drop the mount lower so the tweeter domes didn't stick up though the top of the metal dash and interfere with the dash pad.

https://farm8.staticflickr.com/7926/...5353d4a4_c.jpgUntitled by awesome_adawson, on Flickr

So the one issue I've had is in wiring up the stock AM-FM radio to the amp. I tried to avoid pulling the radio out, so I pulled out the speaker connection plug from the back of the Delco AM/FM. It looks like this:

https://farm8.staticflickr.com/7865/...4159cc35_c.jpgUntitled by awesome_adawson, on Flickr

Not sure what the ABCD refers to, I was hoping I'd see +- signs or at least front/rear left/right... so I guess I have to troubleshoot the plugs and see what works. The Amp has speaker-level inputs, so if I do it properly I will be able to play the AM-FM through the amp and speakers as well.

I was running short on time and had to throw the seat back in, so for now its not hooked up.

I also ordered more boom mat carpet underlay, and a new molded carpet kit from ACC (through RockAuto, $119 +SH, Tax)

Once that stuff arrives I'll pull the seat again and finish up that project.

Re: "Sweet Pea" 1975 Cheyenne 20
 

Also managed to replace a broken passenger side mirror glass, change the oil and filter, and flush my radiator about a thousand times...


Started off with this mess...

https://farm8.staticflickr.com/7858/...0d673202_c.jpgUntitled by awesome_adawson, on Flickr

and after about 10 flushes I'm down to this

https://farm8.staticflickr.com/7834/...5fc7d53f_c.jpgUntitled by awesome_adawson, on Flickr

I am going to hit it a few more times tomorrow then fill it up with antifreeze...Pretty nasty in there. Makes me wonder how long its been since that was changed!

Re: "Sweet Pea" 1975 Cheyenne 20
 

Solid work. Do you have a link for the amp? I’ve got the 6x9’s in my camper truck but probably need a set in the plow truck.

Re: "Sweet Pea" 1975 Cheyenne 20
 

Thanks!

Here’s the amp

https://www.amazon.com/Infinity-K4-1...gateway&sr=8-1

It looks like that model has been replaced in Infinity’s lineup by a non-Bluetooth amp, so be careful when ordering. I found that Crutchfield only carried the new amp, but was able to find this one on a handful of sites. Amazon was cheapest as usual.

I didn’t really know these existed, so when I called Crutchfield and explained what I wanted to do, they had a handful of solid suggestions for Bluetooth amps. JL makes a very similar model. I guess these setups are common for boats, Side by Sides and RV’s, basically allows you to use your phone as the head unit, without the need for an actual stereo.
