I usually replace those grommets. When the original natural rubber grommets break down, they can definitely cause the tuning condenser to sag and move around when you tune it, and other strange things, too.

I buy regular black rubber grommets from Ace. The inner hole is about 1/4 and the groove will fit about a 3/8 hole. Since the original washers are thicker with the groove not in the middle, I get a neoprene washer the same diameter as the grommet, about 1/16 thick. One grommet and one washer together are about the same dimensions as the original grommet.
