I have one taped to the lid of my tool box labeled for starter removal.

They come out easy as pie with a couple of extentions and the RIGHT socket.

Order 3 new bolts for the install if the ones you have are damaged.
If this is correct, then I would visit a tool truck. Get one 10mm spline socket and one 10mm spiral socket. These sockets are designed to work on damaged bolts.

It is possible that some one has created an undersized head which might require some reshaping with a dremel tool. Of course to do this you might have to destroy the starter to make room.
