I know I am looking for part #28550-46031 (thanks CDan!). Anyone know where I can get one? I have scoured the search threads and have read an awful lot about other glow plug options including the "Wilson switch" fix however I do not believe the Wilson switch is the right fix for my 1978 BJ40 with the "B" motor. Any suggestions and/or advice would be very much appreciated! I was scouring the internet and noticed this part number cross references a similar part for Toyota forklifts. Is it possible that this is one-and-the-same?
