Did not see this part on your site.

I think I know what we're dealing with here. I've seen it a few times in the past, but we've never been able to track down an exact match.

I do have some thoughts, though. Let me walk you through my logic.

The closest we have is our 26-446. This looks almost exactly the same except for the style of the front pin; ours has a round "collar" while yours is a flat "T". That means our pivot bar won't fit into that pivot shoe cam.

If the dimensions match up to yours other than the collar, you could theoretically grind the 26-446s collar down until it's flat. Then it would, hopefully, fit in the original pivot shoe cam the same way as your original shoe did. Would that be possible? Take a look and see what you think. Thank you!
