I have these 3/8" x 1 7/8" pivot shoes with number marking 200-794.
Your 15-045 shoe is listed as 1" wide, however my measurement of the old show is 15/16"
Do you have a shoe that is 15/16" wide. It seems tight for a 1" shoe to fit.
These pivot shoes will be paired with 28" red tip spiral balance rods, you have as S900-28.

You will be alright using 15-045. Other people with your #200-794 shoe had no problem. Your shoe might have worn down from use.
