I have measured this part in the attached photos MULTIPLE times. Shoe is 1/2" thick, exactly 1 3/8" tall and is exactly one inch in diameter. Any suggestions for the replacement parts? Most seem to be 1 1/4" in diameter in your stock and that's too big. Any help would be appreciated! I have been to hardware stores and multiple other places. No idea what brand these are. They are vinyl and 18 years old.
