Even though I'm still light years away from finishing, I dragged out the seats that came with my 57. I'm thinking they're possibly AH 3000 from the catalog pictures I've seen, or maybe something else. The covers are decent and the pans are good but the TRF leather seat covers I have will never go on. So how can I find some useable proper seats and who might want mine? Are all the tr3 raw seat frames and cushions the same, or is there a 3, 3A, post 60K difference?
