I once installed a power box off a late 70's truck on to my 72 Jimmy that I used to have, it was a simple, straight-forward bolt on. I believe in the eighties gm started using a "metric" power steering box, you will want to avoid those. The bolt pattern should be the same-4 bolts onto the frame-you should'nt have any problems bolting a newer box on. Check the wrecking yards, tons of 'em are around still.
