[ccomer1955]

I have not found exact matches for the large rubber washers under the chassis and on top of the chassis for the tuning chassis. I've looked at Rennovated Radios and at Old Radio Parts, but the sizes don't match. It is difficult to be sure about the exact sizes since the original ones are so mummified, but they seem to have a 3/8" hole (the bottom ones have a metal sleeve through them). The ones on the bottom measure at 1/4" thick and the ones on top of the chassis measure 1/2" thick.
Any suggestions about finding or manufacturing replacements?
