Replying to How do you remount a binding?

Ive got a unique situation here, ive had bindings on my old Surface Watch Lifes that broke. Took them to a ski shop, and had them put new bindings on. Since then Ive gotten new skis, so I took off the bindings on the Surfaces so they could be paired with my new skis. I see they've plugged the holes where the old bindings were. Since then I've fixed my old bindings and want to remount them my self (dont wanna blow $80 at a shop) on my Surfaces for shit skis. I don't need to find out where the holes are since they've been filled with some colorful shit. I just have to redrill them out. How should I do this?

Also I dont give a shit if I accidentally destroy these since theyre gonna be for urban skis, so dont tell me I dont know what Im doing and should have a pro do it.

+K for good answers...thanks guys
