Many thanks for the replies I received.

A tip of the hat to Brian VK2GCE who suggested that I use chassis grommets!   They worked great!   I used 7/16 inch grommets.   Installation was easy;  clean out the old material and install the grommet.   If the fit is correct, the stud will easliy rotate within the grommet.

The Studs which the dynamotor base clamps lock onto are rotted and are not useable.

Can anything be done about this?

This is not a critical issue for me as I do not use dynamotors with my Command sets;  Even with additional bypass capacitors and more grounding, the noise is not palatable to my ears.....
