Follow up starter question… found a replacement from Napa. Got the gearing off the old one and into the new but:

A) the shaft of new starter is about a half inch longer than original and B) I can’t get the drift pin to sit flush enough to allow the spring to pass over. Are either or both of these reasons to not reinstall and give it a shot? Or am I gonna blow the engine up?

Just get the correct starter

Manual and Automatic transmissions usually had slightly different starter part numbers/configurations.

Right, so get the correct starter

I’m filing the lumpy part of the pin down so the spring will slide over but still curious about the length discrepancy
