Bucket seat retarder spring for 1965 Dart

I didn’t know what they were. They aren’t easy to see, and the plastic boot holds them in until they are upside down. I had to pry the broken ones from my coupe out. I was looking for some other information and found them by accident in the FSM. It’s one of those things that you wouldn’t know about unless you’d had on e apart, and maybe not even then. There is a small bolt that goes in underneath them from the bottom of the seat frame . I have no idea why it is there unless it is some kind of stop for the spring. You can see it in the FSM diagram in my first post. They call it a “lock screw.” They also show that the pivot bolt is two pieces that screw into each other. On my cars it’s a pin with a plated cap and it’s held in place by a metal cap with “teeth” that drives on it for assembly and pries off to come apart. I’m afraid it’s a one or two shot part, and god knows where you find another one.
