I used cotton batting worked great. I will add to take the diaphragm off carefully and clean the head under the diaphragm both of mine was caked up very badly.

You can get the foam at any foam shop. Sticky one side, 10mm, closed cell. Pretty cheap, maybe $10 for 3ft square. Cut to size including screw notches, clean off old with alcohol and stick on.
