They are vibration isolation mounts.  If you don’t use them, you may get to listen to the dynamotor in your headsets via a microphonic tube.  YMMV.

Well, that's ok they're not shock mounts as I don't plan to take the radio up in a B-17!  All I want them to do is to allow the dynamotor to clamp onto them. 

 

How do your replacements install?

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.....
