1965 Dodge Dart Charger

…except now that I think about it even more (this is the problem with the "memory leaks" that develop with age) I am back to thinking the 1965-type mirror control does not use a Tinnerman clip. I didn't have a correct NOS 1965 mirror kit when I was working on my '65, I had a '67-'76 (maybe '66-'76) style kit, and it had the slim-body type of mirror control shown in the eBay auction I linked. That type had the Tinnerman clip, but I don't think the early large-body control (such as the correct '65 control you have) did. I don't find anything that could be this clip in the '65 FPC, but I might in the '68. It's a little hard to tell because instead of "Tinnerman clip" it says things like "RING, door outside remote control mirror locking" and "PLATE, door outside remote control mirror control index".
