I'm restoring an ARN-7 and a BC-433 radio compass and now have found all components for both installations but are missing the plugs.

For both the receivers I need the PL-122 plug for the control connections and the PL-108 plug for the loop antenna
For both the LP-21 loop antennas I need the PL-108 antenna plug and the PL112 for the control connections
So in total two times the PL-122, two times the PL-112 and four times the PL-108
Am I looking for hens teeth or are they around? They sure look to be odd plugs.
The mounting plate for one of the control boxes would be welcome as well.
