I fixed my post, saw it was missing stuff. The links are now fixed and should shed some light on it. Worse comes to worse, an upholstery shop should be able to install them if you aren't able to figure it out or TMI doesn't come through. I wish I could offer more but it's been some 30 years since I've been behind the door panel of a 70s car and my interest then was in fixing the window, not the door panels so I never really looked at them.
