Here are the finished products. The seat on the right has the original upper material (this was originally the passenger seat back cover. I was able to pull the upper cover and foam off of the passenger side frame and switch it to the driver's side frame since the cover was nearly perfect. Both seat bottoms and the left seat back are the PUI pieces. They still need some heat gun time to smooth out the pull marks and wrinkles but they look pretty decent. Here's a close up of the material differences in the 1972 Tetra grain inserts used on the 1972 deluxe seats. You can see that the PUI cover on the left has slightly larger perforations than the pin-sized holes on the original material on the right.
