does yours

Funny thread and I know it's old. I have to many parts to choose from. I am trying to put a 69 Swinger back together that was taken apart long ago, I don't think they had cameras way back then! LOL
I have a 69 plane jane rubber floor mat Dart that has no rear armrests, do you figure on the assembly line, were the little screw clips installed in ALL the Darts built?
I just don't remember if it had rear armrests or not, is there a code on the build sheet that would tell you this?
Thanks all!
