How To: Ruin a Perfectly Good 4wd
 
2 Attachment(s)
While searching the local classifieds for a 67 Mustang fastback or 69 Camaro project for my wife, I stumbled upon this 70 Blazer. Really, I wasn’t looking for another truck, I promise. I have enough going on with my 1970 pickup: How To: Ruin a Perfectly Good C10, but the price was right, so I grabbed it without a real plan of what I wanted to do with it.

The 45 minute drive home revealed what I already knew: it needs a little TLC, and it rides like crap. What to do?

Below is a picture from the classified ad and one from my first fill-up on the way home:

I got it home with no issues, and promptly started tearing into it to see what I’m working with. It’s very solid underneath, with some minor rust issues peeking through a 10 year old, pretty well done repaint which was done in a F*rd color, medium wedgewood metallic blue. The real rust is in the upper windshield frame, as it had been sitting outside for a while. Overall, a pretty solid running/driving truck that just needs some lovin’ to get it right

I kept thinking about what I wanted to do with this old thing and remembered I had seen a new product on the market from Polite’s Deadend Garage out of Biloxi, MS. Pretty slick pieces that take care of upper spring mounting, c-notch, crossmember, panhard, and shock mounting.

These are excellent pictures! They really show how their set up works, thanks!

Looking forward to see the shots of the front suspension 4x4 to 2 wheel.

EDIT: Just saw those were borrowed pics ... I totally missed those when I was trying to get better shots of how their stuff worked.

While I was pondering the conversion, I decided to put together this dirty photo-hack of what it might look like as a 2-wheeler. I was instantly sold. This thread will now serve as a 4wd to 2wd Blazer conversion walk-through, using stock or stock-like parts. There are a few conversions here on the board, including my own previous endeavors, that leave many questions unanswered. I hope to remedy that as we proceed here.

The order has been placed with DEG, so look for updates as the sparks begin to fly :chevy:

Ok - in for this one. I have a 71 4wd blazer running/driving project in the garage right now that I may go this route on... haven't decided what I want to do with it yet. This thread may change that though. You going to keep it 6 lug or swap it all to 5 lug as part of the process?

Plan is for 5 lug, so I can do the torq thrusts. Any 12-bolt or 10-bolt axle from 71-87 will slide right in and are readily available cheap. Even new replacement axles are relatively inexpensive. I have pondered using the 6-lug conversion discs and 15” wheel vintiques steelies with dog dishes, but the 20” TTs just look so good...

azproperformance.com has it for $645 shipped. I went direct through DEG and added a second crossmember for $100, which will locate above/near the spring perches to minimize framerail flex. Also got a set of their front shock relocators for $80.

Jason at DEG was great to talk to, answered all of my questions and then some, sent me a bunch of pics, and offered free shipping. Satisfied customer so far.

Thanks for the link. Im not an Instagram user so I don't see this kind of stuff. I have no idea what size tire and wheel that guy is using but I like the fact that he has some decent sidewall.

Ill keep watching your build here. You do great work

Couldn’t agree more. I see other styles I like, but nothing ever competes with the TTs. I even did a version of the chop with Ramblers, which I like a lot, but they just looked like a platinum, diamond-crusted grill. I immediately deleted it and set the above as the plan of action

Thanks! His wheels are 17” Coys c-55 with 255/50 and 275/50. Proven tire combo that looks and fits right on these trucks. I’ve just gotten so used to the 20s that anything else looks wrong to me now...

Should be an interesting swap. Although, you are not going this direction, I always wanted to see if I could do a swing arm suspension with coil overs on a 4x4. Maybe I'll get some ideas as you progress

Porterbuilt has a bolt-in coilover conversion; not in my budget right now. I think you could also make the NoLimit or RideTech parts work. Either way, trailing arm crossmember and notch placement should be similar/same.

I’m in for this build for sure, to answer your question on your other thread, I really like the TTII’s I have. The only problem I’m having is with the backspacing on the rear wheels and my narrow rear axle I’m running in the burb. They don’t fit at all without running a wheel spacer or adapter which I’m not a fan of. Trying to figure out what I want to do about it now.

Too bad you’re not closer, we could work something out. I could use a narrow axle for my truck...

Great thread!
The only thing I would add to the Deadend Garage parts,... is a 2" lowering block to help keep your ride height low,... with the correct pressure in the air bags.
I'm glad to see someone document a 4x4-to-2wd conversion with Deadend Garage parts.

Keith,... which Torq Thrusts did you order?
The 1-piece VN515 or the 2-piece VN405 wheels?

The 1-piece wheels are cheaper but only come in set backspaces.
20x8 (4.5"bs) and 20x10 (5.75" bs)

The 2-piece wheel comes in 20x8, 20x9.5, 20x10, 20x12, and 20x15 with a large variety of backspaces.

When I ordered mine for my blazer I specified the backspace I wanted, since they were going through the custom shop anyway.

My TTII’s are the 1-piece VN515 that I had on my 68! The backspacing worked on that truck because it laid frame and was going to have a modified bed floor and wheel wells. The 5.75” backspacing on the 1-piece 20x10’s absolutely do not work on my 66 Burb with the narrow rear I’m using without an adapter and I’m not interested in cutting into the Burb to make them fit. I also don’t want to change out my rear as I have a good amount of $ tied up into rebuilding it. After doing some thorough measuring over the weekend, I solved my problem yesterday when I ordered 2 20x10 VN405 2 piece polished TTII’s from Travis at Pro Performance. I really liked the look of the TTII’s on my Burb so I just ordered a pair with the exact backspacing I needed. They should match up close enough to the front 1-piece wheels that no one should be able to notice a difference. I’ll be putting the 2 1-piece 20x10’s up for sale after I get the new wheels.

Good to hear. I was afraid you were going to change to a different wheel.
Those look so good on your suburban!

If I bag it, it will definitely get 2” blocks. Right now, probably going static, as I have most of the parts on hand... unless I can find another $2-3k in the budget to bag it properly.

I’ve been wanting to document a conversion for a while now; I’m personally more interested in properly locating the front crossmember for prosperity, as there seems to be lots who have done it, but no definitive guidance. The DEG parts should make the rear a snap; remains to be seen!

Funny you mention that.
I've always thought about these conversions in great depth.
For me personally,... I would move the entire crossmember forward 1" to help center the wheels on low trucks.
I know this means, moving sway bar mounts, idler arm holes, and the steering box holes,... but to me it would be worth it.
Especially if you could weld and do it yourself,... which I know you can.

I remember seeing this mod years ago on a squarebody blazer converted to 2wd.
But I can't remember which magazine it was in.

I think you could get away with moving the whole crossmember forward a bit, without interfering with the steering center link. Possibly combine that with the lower control arm “caster mod” for more centering. We will see how it pans out, but I will play with it a bit to see what works best.

If you think about it, moving the whole crossmember forward isn’t a whole lot different from using 1” forward tubular arms, as far as steering linkage geometry is concerned when related to the pitman and idler arm locations (someone please correct me if I’m under-thinking this). Stock type anti-sway bars can have the ends trimmed and linkage style bars might be able to absorb the difference (or have bushing locations redrilled, as you stated, thankfully, I’m starting from scratch there).

All that to say, it may not be too terribly complicated to gain that extra inch. 104” wheelbase is stock, so probably somewhere in the neighborhood of 105” will look “right”. I’m pretty excited to finally get to play with one (the yellow Blazer was already converted when I bought it). Let’s find out together :chevy:

You might have the inner tie-rod ends get too close to the crossmember if you move it forward, but that should be able to be "clearanced" or notched to provide enough room for them. Another issue that would come into play only if you are bagging it, is the fact that the steering column shaft may interfere with the upper control arm when laid out. Again, an easy fix for someone with your particular skill set.
