What mini starter are you using ?

Nippondenso makes the mini starter for Chrysler. You can get one at any parts store. Just tell them you have a 94 Dakota with a 318 it should fit. The last one I put in a 360LA engine I had to grind down a small bump on the block that would not let it sit flush but it was no big deal. They are about 75 to 100 dollars.
