We are looking for these parts, we see similar in your catalogue but none like this. There is a stamp on the glass that says GMAC028711, Alcan London, 06-91. We can't seem to find any other part numbers. Hoping you are able to help.

This looks like an older model pivot shoe that isn't made anymore, but one of ours may still replace it. Can you just tell me its width and thickness? Can you also show me a picture of the pivot bar that goes into the cam? These details will help us determine what you need.

Thanks for the additional information. Take a look at our 15-121 pivot as a possible substitute. As for your pivot bar, be extra careful when reinstalling them. We have not been able to locate these type of pivot bar replacements.
