Steve, G-bodies are from 1978 - 1987, also known as GM intermediates. The S-10 was built from the GM Metric parts bin, and all S-10 chassis from 1982 - 2004 are fair game for donors. The S-10's after about 1985 have a different Lower A-arm bushing when GM upsized one of the A-arm bolts from M12 to M14. Beyond that, they are the same. The Gen 3 Camaros also are built out of the same parts bin sharing brakes, lower a-arms, steering boxes, etc.
The other advantage is that well over 500,000 racecars running in North America are based on the G-body chassis. That opens a whole list of tubular A-arms, coil overs, brakes, sway bars, etc that are out there.
