Those things are a real bummer to drill out. Most of the time when you get them drilled out the holes are to big and the new pins do not fit tight. I would see if you can find some different hubs and get some Aisin hubs.

A good source for used parts here in California is Dave'z, I know that he has them. If you cannot find them up there give him a call.
