Thanks for the information. I was just researching pictures of interior and they are 70 seats. Everything is there but I think I am missing the spring that connects the rails to slide together. I picked these up for $300 and they are not in too bad shape. For now, I think I will just recover them. The backs are scratched up a little bit but not in bad shape for 45 years old. Also missing the tab on the passenger side slide handle.
Thanks again for everyones input.
