mini-starter questions

Pull a part, $15,00 ea. Got two, one worked fine one was dead. Took back the bad one and they gave me credit till they get in another Dakota. As the guy's have said the V6-V8's appear to be the same. The front wheel drive use the same starter motor but the mount is different, has three bolts. I took one apart to see how it works, and clean the commutator. The brushes have a heavy spring so you need to push them up and hold them with paper clips or piece of wire to get the armature back in the housing. Just push them up till the wire will slide under the spring at the top.
