Do you have an old school starter/alternator shop in town? If so you might swing by and pick up something from them. If it is an old school place with a guy with gray hair behind the counter he might have some rebuilt ones that will last forever. We have a place like that around here and the guy rebuilds alternators and starters like they are swiss watches. He also doesn't charge a ton. I also give him my old cores rather than throw them away since he takes them apart and uses what he can.
