I'm looking to replace the top lever spring. Everything is straight forward so far, but I'm at the point of removing the top lever screw (from the underside) in order to remove the cam that holds the locking latch in place. The screw looks to have a hex socket cap, but it seems stripped out. If anyone can offer a suggestion, I'd appreciate it. I was thinking about dremeling a slot in the screw head to accept a flat screwdriver, but that is stretching my skill set a bit.

Thanks in advance.
