My buddy has a 2wd Suburban with a healthy 350 but a blown tranny. He asked me if we can take all my old 4x4 Chevy parts and use them to convert his Sub to 4wd. So that is my question: Can I practically convert a 2wd Sub to 4wd? Will it be bolt on and go or will there be custom/fab work to be done? I am just trying to judge the scope of this project before it even gets off the ground. Parts I have: 4wd steering box, 10b/14bsf matched gears, 700r4/208. Parts I need: front springs and driveshafts.
