New Here, building a 71 air cab big block 4x4

[Davemotohead]

Hello,,I am new to this forum and building a 71 396 4x4 air cab long bed,,I am getting ready to swap the 6 lug 1/2 ton axels out and put 8 lug 3/4 ton axels in from a 85 suburban,,the front looks like a direct swap,,the rear seems like the springs are to far apart and might need the spring mounts moved on the axel, Just wanted to say Hello and here are a few pics of the truck! I also have a restored 49 - 2 1/2 ton flat bed and about 30 other chevy cars.
