I luckily bought it almost finished. I used stock rears and replaced em when they broke, but I think an S-10 rear is a close fit. The firewall was notched a bit for the distributor and there was a (Knuckle, joint, ?) put on the steering shaft. Its just a lot of measuring and mocking up, but at 2,080 lbs or so, It was a wicked ride.
If your interested, I'll try and find this old Chevette, V8 swap forum. Let me Know. HG
