Differential Swap/axle concerns
I own a 1983 Chevy van with a std rear end(3:08 gears) and I tow a 31ft airstream, travel trailer, with it. I was going to buy a retired 1 ton work van for a couple hundred dollars and swap the rear end and out of it. Being that it is a 1 ton van it has eight bolt hubs / axles if you will, my van is a 3/4 ton and has 5 bolt hubs / axles. Can I take the axles out of my Van, 1983 3/4 ton 5 lug..GM 10 Bolt with 8.5 ring gear...and insert them into the larger rear end that has 3:73 gears in it. I know it has that ratio because of the option sheet but I don't know if it is a Dana Rear end or what. I wanted to get some tech advice before I pay the two hundred for the van and haul it home for disassembly.
