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. http://www.dxham.com/CollinsV20-2/2008-11-23/008.JPG http://www.dxham.com/CollinsV20-2/2008-11-24/003.JPG 73, Al
