Forget the upgrade, put your old starter back in. It could probably stand to be torn down and cleaned up, get the bearings relubricated. A friend gave me two stock gear reduction starters, you can't use them with tti headers. They looked terrible, had been laying on the floor for years. Went through them and I now have a spare, cause the Dakota is coming out of my stock '72 318 Dart, I like the sound of the old starters. In the old days, if someone was starting a Mopar, you didn't even have to look, you knew it was a Chrysler product. Now I have a spare starter for my '69 that has tti headers.
Don't believe that the Dakota is clockable, you would have to buy aftermarket race stuff. They are expensive.
