To my knowledge, you aren't going to find an automotive starter to cross over to the Mitsubishi's. I know that the Ford Courier alternator crosses over to some of the mitsubishi tractors, used this one myself but I've not heard of an automotive starter cross over. You may want to post this in the Mitsubishi forum and see if any of the gurus there can give you any further insight on that but I have owned a number of larger model Mitsubishi's and follow the Mitsubishi forums pretty closely and don't recall anyone ever having any luck doing this. Give the Mitsubishi forum a shot and see if anyone has had luck doing this. The starters can usually be rebuilt, not always cheap though and I assume maybe you've received a quote and are trying to find a cheaper route.
