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?

I'm currently working on recapping my BC-453B Nav Receiver.

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.....
