New Parts
Thank you! Let me know if you need more info.
I think we can help with these parts, but Full-VU pins are actually kind of a dying breed. There aren't many of them left; we only carry one pin under this brand and it doesn't appear to match any of yours.
Before we go any further, I'd like two dimensions from each pin you want to replace: the diameter of the metal pin itself and the diameter of the top nylon cap. Not that I mean the very tip of that nylon part; if you think of it as a hat, I want the top part of the hat, not the brim. Hopefully that makes sense.
Basically what these dimensions will tell me is how your pin fits in the door and how it fits in the track, which are the two most important functions for these things. I don't want to make any promises this early, but once you get me those measurements I'll do my absolute best to find something that will fit.
The top cap is 3/8
The length of our current pin is 5 inches from the start of the cap down.
Perhaps I can help. The bottom threaded adjusting pin you show looks similar to our 21-002. For the other top pivot pin with the spring, however, I would like a better view. Like Tom said, these are harder to come by these days. I also need to see the guide pins that slide in the track when you operate the doors. I know it's a lot to ask, but seeing them out of the door would be the biggest help.
