Is it possible to put any GM axle on a squarebody?

[Messenger]

I want to put 3.73 gears on my 4x4 1983 Chevy. I was wondering if it is possible to take a front and rear end from say, a 90's 4x4 Chevy, and swap/bolt it on with a bit of fabrication? Is there any how to's on this site? Thanks for any help.

I would say the rewards would not be worth the work.

Leaf spring perches for the rear would need cut off, spaced right and re-welded on. Hopefully the track is as wide as it would need to be. Front from a "90s 4x4 truck" is IFS you know that don't you? I have no idea what kind of crazy fabbing you'd have to do to make that work, if it would work at all.

Oh, didn't even think about it. Thanks, scrap that from my ideas list.

73-87 1/2 and 3/4 ton 4x4 trucks wil be a direct bolt in front and rear, 73-91 Suburban and Blazer will also bolt right in. the 77-91 1 ton Dana 60 front wil also bolt in. anything 3/4 ton and heavier will require spring plates that match the axle.
