i went on a mission today for an fe starter for the 12 volt case. first two stops all starters had a shorter case, unknown application, friends junk piles. next looked at an old motors manual and saw only that fe starters all had that "half a potato" can on the side with the magnetic switch, not the one either. last stop was an old junk yard that also told me all fe starters have the "potato" on the side. finally we went to his junk pile and found two without the potato, and with the long shaft for the bendix. y block, or early fe i dont know, but i have two here now. will report back when its spinning!
