I need thicker pivot shoes for top windows, do you carry 1 1/8" thic shoes?

My windows have deeper rear channels for top sash of the window (aluminum double hung). For the front I was able to use the 5/8" Pivot Shoe, an exact replacement.
BUT I noticed the rear track is deeper and would need a pivot shoe which is 1 1/8" deep (See attached photos) and you don't list any that size.
Is there some type of plastic (snap-on) size doubler available?

I haven't removed the original rear pivot shoe yet but it appears as if it might be two separate parts joined together somehow. I don't want to remove the old ones until I have something to replace them with.

Do you have any suggestions or advice for me? Is this a common window design?
Thanks so much in advance. 5/8" Pivot shoe fits bottom windows perfectly.

Thank you for your continued patience. It took some tracking down, but we think we may just have found something that can work to shim out your pivot shoe, just like your original setup. Please give us a little time to have it made for you and I will let you know as soon as it's available!
