V8 acc. cable and pedal assy.?

It sounds like the same pedal assembly as my 65 Barracuda but I thought they were different. Anyway, if it is like mine, the pin should have a spring clip attached to the head and when it’s pushed it locks into the floor bracket. If you use it without the clip the pedal will occasionally come loose from the bracket (my carpet installer broke one side clip off, and it never worked after that). I got a replacement from the Junk Yard but Early A’s getting very hard to locate these days.
