I bought a used Trig TT22 transponder but it didn't come with the semi-circular mounting adapters ("circular hole adapters"). I need these as my install will be going into a round hole.

I am hoping that someone somewhere installed a Trig transponder (or Trig transceiver) into an oblong hole and thus has laying around an unused set of the mounting adapters that I could buy from them.

Please let me know.

Thanks, John (OHM)
