1970 c20 dually

[tmg619]

Hey guys im new to the site and am needing help. I have had this truck just a little over a year now. I have stripped it down to the frame. Had the frame blasted and painted. I have a engine and trans out of a 2006 tahoe thats going in it. I am ready for assembly but the issue is the suspension. I wanted an ifs front suspension for this thing but they dont offer it in 8 lug. I could go 5 lug ifs but i have the cab lights on the truck and i thought it would goofy and take away from the truck if i didnt stay with the 8 lug. Ive been stuck at this point for a while now and dont know what to do. Also the rear end is i think the eaton which is hard to find parts for or convert to disk brakes. Any help would be appreciated. Pics coming soon.

Most people use the front suspension out of the 73-87 trucks it bolts in,Yeah the eaton rear is hard to find any parts for i would look to swap in a dually rear end from the 73-87 trucks.

These bolt in withoit fabrication?. I have a lot of experience in fabrication but i dont want to fabricate anything major just small stuff. so im just looking for something that will bolt in like oem parts but updated.

Sell the Eaton and find a c30 frame. That will give you better brakes, the 8 bolt hubs, and everything is beefier over the 20 frame.

I put disc brakes on my full float 14 bolt for around $400. But, I had to grind the Monty calipers to make the stock 16" wheels work with the massive spring pack.
Most newer trucks have a 11.5 with disc brakes and that may be a better option if you want the easier maintenance. No idea if the stock 16" wheels will work with the 11.5. I am sure someone can chime in.
But, 14 bolts and 14 bolt parts are everywhere. Good chance you can find one with the ratio you want. If I went with a 17" or larger wheel the calipers would not have hit. But, I have 20 of the 16" dually rims collected at this point and 16" tires are cheap.
