What's The Deal With The Mopar Mini Starters?

I have too through the years. Never had an issue.

The first mini starter I ever got hold of had that protrusion on the nose.

After grinding it off it worked fine.

I posted about it on FxBO but several folks basically said I didn't know what I was talking about.

To them I now just wannna' say- ptptptptptptptptp, and na na na naaaaa na!!

Yup, I know for fact there are at least 2 different designs of nose.
One supported by a socket hole for the nose in the bell housing and one that isn’t.
Unfortunately I don’t have any specific info on what only fits what.
