Also, another thing I do not like about the mini starters is, we have been finding that not all of them work on our older Mopars. I've seen it first had more than once and a couple other members have as well. Some of them do not throw the starter drive out far enough and either barely engage the ring gear, or not at all and the starter just spins. We had that happen on a friend's 68 D100 with a 318 and auto. The mini started would not engage at all. We went through FOUR and I finally gave him an old big style Chrysler started I had and it worked just fine. So be warned, you "could" run into the same issue.
