What is the diameter of the insulator you need? I have one that looks just like the good one for the back modulator tube. It's in the Bauer 707 I'm rebuilding, and I will not need it in the final "product". It was a feed through to the built in dummy load. The one I have is 1.125 dia. at the base with a slight draft angle to the top, and about .75 deep (panel to end of ceramic) looks to be 10-32 threaded rod.

I need 2 parts to complete my 20v-2 electrically.

A safety interlock switch for the rear left door and the ceramic insulator
that brings the HV to one of the modulator tubes.

Here are pix of the parts I need.
