I have a 71 that I need to get a lot of the plastic pieces for. I see a lot of different things on the plastic pieces for these cars whether they are bad or good. I need sail panels for mine. Are the OER ones pretty nice? I see others listed online but with no brand connected to them. Also, I need to get the rear panels by the rear seat. Are any better than the others? How about the door panel stuff? Is most of this stuff produced by 1 company and resold by everyone? I haven't decided on the seats yet. I've been leaning towards some new procars, or corbaeus. For the price, they may be better than re doing my originals since they are pretty sun baked. Thanks in advance, Ryan.
