Yea, look around for an automotive electrical shop, or armature shop. I've had several rebilt, typically $75 to do them. The parts will almost cost you that much if you try to do it yourself, but if you screw it up, you're still out the money. Every town has a couple of automotive electrical shops. If you cannot find in the yellow pages, ask at an old time car repair shop, where they have starters rebuilt. Someone will know.
