I have a factory Dakota starter on my Savoy. Not sure what year it is but I put new contacts in it 16 years ago before I installed. It is one of the few starters that will fit with a 143 tooth flywheel and a steel bell. It may even be from a V6 because it's pretty small but it starts my 493 even on 90 degree days.
I can't stress enough that you buy a real Denso unit made in Detroit or Japan. Stay away from the many Chinese copies at the parts stores because they are hit or miss for quality. Mancini Racing sells the real thing but be prepared to spend twice as much money. You can also get a Denso re-man that is like a brand new one.
