The earlier models had the aluminum side mouldings, even up to 73 I think as have a full set from a 73 Runabout, which I may sell. It may depend on where the car was manufactured. They had bolts on the ends and clips in between along the door. I'm pretty sure the end mouldings in front and behind the door have one bolt and a spring clip. My 74 Runabout came with the adhesive type side mouldings. As far as the Pinto emblems go, those are called barrel nuts that the small pins press into. Some are metal and some are plastic. I found if you gently pry the emblems off a little at a time with something like a gasket scraper or a trim tool they come off without breaking. There are tons of those around if you break one, and you caoul easily find one from somebody here in the club. I have several myself.
