I have a set of Cobalt SS (Recaro) seats I made work to bolt in to the g-body mounts using feet off g-body tracks. Still haven't had them in besides test fitting to see how I like them but they look real good IMO. I agree on the GTO seats being a bit too big for the g-body interior.
Hi guys; Picture was after return from interior shop 09. I had just got them back with a fresh leather surfaces. Originally the seats were fabric & when I ordered the car I ordered the car March of 79 I ordered the seats a few weeks later. So weeks later the seats arrive before the car, yes I've had the seats just a few weeks short of 40 years! Ole' Bob.
