I will not recommend you buy a "rebuild kit" off the internet. If you don't have the instructions and tools to recondition and test every component of your starter, you might end up with the same as you currently have even after you install the few parts in a kit. Your service manual should have a section on testing and rebuilding the starter to give you an idea of what is involved. If I was you, I would at least want an estimate of cost for repair of the starter from a local shop or two before looking for a replacement. I suggest you check around your area and find a shop that rebuilds starters, generators, alternators, etc. As for what is local to you, I can web search for starter and generator repair shops in Kent, WA and some show up. I can't check them out or give you a good suggestion as I am on the other side of the country. You can web search, ask at local parts stores or garages, equipment dealers or contractors that have some heavy equipment for suggestions of such shops in your area.
The Delco Remy 1107064 should not have a two bolt mounting. It is not safe to trust stock pictures in ads. If you decide to get a replacement contact Lavoy, the owner of this site, to see if he can help you out. I don't know if he sells rebuilt ones on an exchange basis or not. He prefers direct contact on parts needs, not posts in the forum or PMs. Call him at 701-361-1006 during CST business hours or send him a direct email:

There are a few members out your way. Hopefully some of them see this and might be able to point you to a good shop.
