This is a new M-series 24 volt ignition switch. This is the main switch for your M-series military vehicle. This particular style has the rubber Packard style connectors. These were used by the military to upgrade and replace the Douglass style when the compressed sawdust backs fell off of them. This will fit the M38, M38A1, M170 , M151 jeeps, M422, M422A1, M37, M715, and many of the larger trucks. We offer the lever for these if needed in a different listing.
