70--71--72 seat questions, pic request?

I'm not sure about converting those to the 70-71 seat style. Your 72's have the button integrated in the seat itself. The 70-71 seat release button is a separate metal hinge.

With that said, if all you're trying to do is cover the seats in 70 patterned vinyl, I'd call Legendary and ask them.

Here's a 70 Duster seat and it kinda looks like the release mechanism on it is down lower on the seatback than yours :scratch:

Good luck.....maybe try placing an ad here to trade them for 70-71 style?
