Uncle, be careful when buying new(repro) seat covers. Some of them do not use the proper "dielectric" seams and they look cheap. I received a set that had the proper grain and proper fit, but the dielectric seams did not exist, they were just flat. I think dielectic seam is the proper termanology??? Anyway, buying new springs, foam, etc.. is going to cost you big bucks and I have also seen a set of chevelle seats with that new reproduction foam and they are really firm and high! Personally I couldn't stand it if my knees touched my steering wheel. I guess I do not have to worry about that since I have a tilt column in my '70 454.
I have a '69-72 A body seat from a GTO. this seat is identical to the chevelle seat with the exception of the seat cover. Anyway, it is complete (no headrest) and the foam is excellent and the springs are solid and not broken. It also has good plastic and good tracks. I only have this one seat for sale. I am asking $60 for it plus $25 shipping. It is the passenger side seat, but the springs and foam are good for both seats. If you are interested, please email me. I also have a guy interested in just the plastic, so you could sell the plastic to him and make back some of your investment. I have a picture of the seat. thanks, Hugh. I also have a '70-72 tilt column for sale ($125) firm.
