I am ordering pivot shoes 9/16". #15-121. It has can slot with center tooth of 5/16 wide and 3/16 wide. What pivot bar goes with it? And do they come in rust resistant and does the screw come with it. If not what screws do I need?

It's difficult to identify what you have due to the heavy corrosion, but we do carry the stainless steel 26-437, which comes with a screw. Please compare it to your own hardware to confirm if it can work.
