I've done the drill thing also, many many years ago. LOL LOL LOL But if you can get the spindle out, you have good shot of getting the cups out also. You will probally want to run it by a shop afterward to have the threads rechased, aside from that slow and stead wins the race here.
One guy i know got his out by drilling oppisate holes on the cup and using a very stiff spanner to break it loose. ALso he soaked it in PB Blaster to help break it free.
Good luck, keep us posted.
