I may have the chance to buy an old (late 70's or early 80's) Suburban for 500 bucks. The guy knows that it is a 4X4, and that it ran when it was parked about 3 years ago. He doesn't know much more. I was wondering if anyone knows what axles it should have under it, and if I can use them on my 1970 K5. Would there be many mods needed, is it even worth it? I know this is the 73-91 board, but I needed as much help as possible. Thanks. Diesel Everything's bigger in Texas!
