Can anyone tell me about rpo 603? I've got a 72 Cheyenne that I'm making future plans for. I'm trying to gather up the correct interior parts and want to know what this code entails. It's hugger orange with a white headliner and door panels with black carpet and black dash pad, but the seat is missing. Here's a pic of the spid:
Are these things I've listed likely original? And what about the seat?
Any other comments about the spid are welcome as well!
