Here ya go. This was sent to me a while back by another member.

the screws come from Totally Stainless, 1945 Heidlersburg Road, Aspers, PA 17304.
They are #10x3/4 Square Drive Truss.

Take out a few at a time, clean and polish the area, use a dab of RTV on the screw when putting them in.

Hopes this helps. Beep
