I have a 71SS project car that originally came with a bench seat. Both seats were gone when I got the car. I have a chance to purchase a recovered 72 bench. Are the seats exactly the same ?? (height, size, headrests, etc.) According to J&W...the 72 buckets were larger in 72....not sure about the bench, though. It's a good deal, but I don't want to do it if it's not correct.
