Tap the rolled pin out to remove the oil stick from the yellow handle.I used a small punch the same size as the pin, lightly tap but firm. Also remove the rubber o-ring from the yellow handle, you'll need it on the new Shelby handle. To put the oil stick on the Shelby piece you'll need to get a very small allen wrench and back the threaded screw out. Then insert the oil stick, and re-tighten. Its a little tricky to align, but not hard. NOTE: On the Shelby handle, thats not a hole you're seeing, its a threaded allen head screw.
