[Fast Corners]

I have never had to drill one of the pins out...maybe I'm just lucky. My trick is to soak it with PB Blaster and then with a flap sander or a dremmel grind off one end of the pin flush with the clutch arm. Then when you apply the drift and the hammer to it, it will not mushroom out and bind in the arm.

BTW make sure that you use a correct roll pin when reassembling it. I have seen more than one kit which did not have the right pin in it. The correct roll pin looks like a rolled up newspaper from the end view perspective. An incorrect pin is an open "C" shape. These can fail over a period of time with some very, very unfortunate results.
