Alcoa pivot shoe

Recently I purchased some window repair parts from you to evaluate the compatibility with my vinyl windows.
The Tilt Window Latches and the Spiral Balances work great. (I did have to modify the current pivot shoe to assemble the spiral balance to it)

When trying to determine the correct Pivot Shoe, your 15-045 Pivot Shoe, 3/8 Thick appeared to be what I need.
While it is slightly different than the one in my windows, It would work well except the ?slot? for the pivot bar is just slightly too small, width wise.
I have included a photo with the desired width dimension shown. The groove in the window channel for the shoe is slightly less than 1-1/8?, but the 15-045 shoe does lock when turning the pivot piece.

Might you be able to determine if you have a Pivot Shoe that would work?

I haven?t found any parts marked with the same manufacturer of my windows, which is Alcoa.
The pivot bar is held in place by 2 screws and is 5/16 wide. It looks like your 26-040 bar.

Thanks, that looks like it might work.
