70 Suburban on a 99 frame and drivetrain

[Dying2Live]

Hey everyone it's been a while. I'm looking at buying a 1999 2wd suburban. I was going to pull all the drivetrain out of it, the interior, possibly the dash, wiring harness rear air and whatnot to use on my 70 burb. What I'm curious to know is would the '70 fit on the '99 frame?? I don't mind moving or fabbing some body mounts if needed, just curious to know if anyone has done this on theirs and what I'm getting myself into. Thanks in advance.

It can be done as long as you have time, patience, and fab skills. I've seen it done in the past

Do you think it would be worth it to have the new suspension and frame, or would you keep it oldschool?? Thanks for the opinions.

It kinda depends. the 67-72 suburburbans have a 127" wheelbase, so the newer frame will probably have to be modified for the wheels to be located correctly.

Another thing, I believe the newer 1/2 pickups us a 10bolt rearend, and I think the 12 bolts that were under most of our old trucks are stronger. Also, I think the trailing arm suspension is better than leaf springs (if you have trailing arms).

When I get a suburban, I'm going to try to find a 3/4ton 4x4 duramax chasis and put the 'burb body on that. My main reason is I want the IFS 4x4 setup and I think it will be less work to get the body on the frame, than the engine and front suspension on the old frame. But with a 2wd I don't see a lot of advantage.

are you sure that 99 burb is not a 4wd? i know they still make 2wd burbs (my preference) but most of the trucks came with 4wd by the late 90's. i would just change over the chassis rather than trying to hack up a totally different frame to fit. its easier to drill a few mounting holes and not have to worry about body fitment. the 67-72 2wd's have a superb suspension (just need a sway bar) but the 99 burb will have front disc brakes.....i'd swap those parts!

maybe a 92 burb conversion frame would be less time consuming.

You get TBI and all the modern upgrades

Yeah, I'm sure it's 2wd. I like the idea of just pulling the body off and putting it on the new frame. How much of the front end will bolt onto my old frame if I use it. I'm planning on pulling everything that I can off of the '99 and putting on the '70. All the drivetrain, break stuff, axle swap. That's one reason why I'd be more interested in swapping the body rather than the rear end, engine, tranny, front suspension, and all that jazz. Thanks for all the comments guys, keep your thoughts coming if you have any more!!
