Need SW4A and B (mode switch) for Ranger I and panel meter for Ranger I. Do you have a parts unit that I can get the foregoing parts from. Does anyone know of a source for the mode switch SW 4????? Does anyone have just rear wafer (SW 4, Wafer B)? I am desperate for the SW4B wafer and a panel meter. Please help me find these items. 73, John, K5PGW
