Hi, I'm in mtl, my seat bottoms were rusted out, I made new ones, I'm lucky, I have access to a bender and welder at aircraft museum, the only part of the old I used was
the upper back on the frames, I looked at racing seats before and do not think they will work, they do not go back far enough, on this car every inch counts, I must admit
it took a lot of hours to measure/cut and weld, I have just glued on my old foam/covers and am very happy that it all fits, I have a few cover foam parts left over from a 2nd
set of seats I had, if u need any let me know.
