Amateur 1970 C20 Longhorn Build - The 1947 - Present Chevrolet & GMC Truck Message Board Network

70C20Longhorn · 01-13-2016, 08:44 PM

Hi everybody! I've never posted on one forum before but I am in need of help building my truck. It's a 1970 C20 Longhorn 350 4 bolt with and SM465 Tranny and HO72 rearend. I bought this truck the the body in primer and the frame painted. Everything was there but was all in boxes, so what I need is help figuring out the parts I don't know and where everything goes. Will be posting pics soon. Hopefully I'm doing this right on here.

Well we are looking forward to the pics. Some of the guys on this board can put these trucks together with their eyes closed =)

70C20Longhorn · 01-13-2016, 08:51 PM

Here's some pics of when I got it.

70C20Longhorn · 01-13-2016, 09:05 PM

Painted the cab with Duplicolor Paintshop Jet Black with black holographic metalflake.

70C20Longhorn · 01-13-2016, 09:35 PM

Need help identifying these parts. Pics of where they go would help as well.

70C20Longhorn · 01-13-2016, 09:43 PM

A few more unknowns

70C20Longhorn · 01-13-2016, 09:47 PM

Few more

70C20Longhorn · 01-13-2016, 09:54 PM

Last pics of unknown parts.

hugger6933 · 01-13-2016, 10:20 PM

The unknown pics are, Air cleaner spacer [goes between carb and breather], Next is the pedal pivot pieces then the next two are clutch bell crank stuff.The pics with the curly que looking spring goes on the right had side behind the seat it is the jack or lug wrench spring [holds it in place]. Now I'm going off memory and starting to forget witch order the last pics are in but I think the next was a slash shield [gravel shield] goes in the bed behind the wheel humps underneath the bed.

hugger6933 · 01-13-2016, 10:24 PM

The flat square tabs hold the gas tank firmly in place the valve may be a diverter if the truck had two gas tanks at some point or maybe a butane burner system. The round washers goes into the bed wood that holds the bed on the truck and the round black "biscuits" are cab or core support mounts.

Heat shields for the spark plugs.

First picture shows booster bracket bellcrank (Circled)

Second picture shows Jack tools & bag retaining spring.

hugger6933 · 01-14-2016, 08:44 AM

Oh and those long things with the wheel hump cut outs go in the back

**LockDoc** · 01-14-2016, 11:23 AM

-
The rectangular plates with the single hole hold the fuel tank in place. You should have a 5/16 bolt for each one of them. The bolts will have a pointed end and a built in washer that has serrations on the underneath side.... A couple of the plates are circled in the picture.

Thanks everyone for the helpful info so far. I'm sure I'll be needing more help as the build progresses. I'm only 22 and don't have very much experience with older vehicles. Hopefully I'll get it running sometime the end of next month. Also where do you guys get those prints/schematics? I have a book that red on the front with about 1000 pages abound I didn't see any of those.

kehstr · 01-14-2016, 12:35 PM

subscribed to help if i can

If your book is the Truck Assembly Manual that is where the scans came from. I have the CD version and you can actually do a search in it for key words. That makes it really easy to find stuff in it....

Apologies if this is considered hijacking, but is this cd from Amazon the one you are referring to LockDoc?

CD-ROM 1967-1972 Chevy GMC Pickup Truck Assembly...

Sadly not yet. Cab is jet black with black holographic metal flake. Inside is championship white with white rustoleum marine epoxy paint. Got drivers door done as well. Not a lot of time and small budget lol. Typical project.

Just got done painting these. Going to install tomorrow. Need to paint the parking brake next.

70C20Longhorn · 01-18-2016, 08:15 PM

What are these two parts? I assume the line is part of the fuel system.

**kwmech** · 01-18-2016, 08:19 PM

Top picture is the power steering return hose, lower pic is for the air cleaner assy--hot air tube from the exhaust manifold

AND being a 3/4 ton the rear axle you have is most likely an HO52 not a 72
