1957 or 1958 is a major turning point for these cars. If your car has the wide mouth then you need the newer seats which are way easier to find, just ask John. If you have a late 1957 small mouth, then you could have either seat in John’s picture. There might be a different seat for a 1954 tr2 I just do not know, but as a rule the 55,56, and early 57 are like the tr2 seats in Johns car and are very rare, and I do not think anybody makes them new. Plus, on the early seats, both seats are the same in that one does not tilt. It depends on what you have and how much work looking you want to do if you have the early stuff. It sounds like Marv has set of the early ones.
Anyways I bet somebody is looking for some bug-eyed seats, so you should be able to maybe break even there. I just finished my seats and made my own form kits with cotton batting and foam and it was not difficult. I will post them but first I need to delete my old pics form room. The hardest part is cleaning up the frames and repainting them once you find some.
