My barn door contacts are shot. Does anyone know the part number OR true name of these spring loaded contacts mounted on the right pillar. I have tried googling variations of "barn door contacts" and I am not getting any decent hits for sources to buy a replacement. I am also looking for the assembly that prevents the door from over swinging. It also locks the door in an open position. It looks like a metal strap. Are these parts junk-yard finds only? Any help truly appreciated.
