Which mini starter? Big diff. in price

[Kilrbee1]

While I have the headers etc. off the 440 in 69 R/T to replace motor mnts and starter, I was going to put the ministarter on it as it appears this is the way to go. Problem is I read the various posts that they're all the same from the minivan to the Dakota but can't find specifics on which engine, year, or vehicle is the one to use either for performance or savings. I looked at the 96-98 Dakota 5.9 units and the 95 Dakota 318 starter. Looked the same outside except terminal mounts but one was $77 and the other $50 more both rebuilt Advance lifetime warranty. Gotta be something else different for the money. Are they all the same or not or will some as I read allow you to loosen bolts and rotate for header clearance? I need to get one asap and back on the road so any application specific info. would be appreciated. Thanks
