Have done dozens of these swaps and can state NOVA is the way to go. S10 too narrow, Camaro/Firebird/Trans Am too wide. Nova just right. Advise you level frame of donor car and write down the caster, camber, and anti dive angle. The camber will stay pretty much the same but the caster and anti dive can change according to the angle the clip is attached to the AD frame. To position the ifs the same as the factory axle and save lots of measuring run a pipe/bar/angle out from the top of the cowl with a cross bar that has two plumb bobs hanging exactly the width and wheel base as the straight axle. Hard to find but 1974 and older Novas had rear mounted steering boxes and 75 and newer have front mounted. Steering shaft easier on rear mounted.Pictures are on a 49 Studebaker but procedure is exactly the same as an AD.
Plumb bobs were set up on the OLD STRAIGHT AXLE:
