Pivet shoes that have the measurements on the images and I believe the primary measurement is the thickness at 3/8" for the broken pivet shoe.
I also need cam pivet bars that attach to the bottom sashes of these windows and look similar to part # 17-093 on your website, but not sure if this is the exact Caradco type part.
If you have these parts then I would order four of each type and please advise.
