I carry a couple of extra 8 mm screws for the CPS just in case I drop the original when I'm either removing or installing the CPS. I've got an 8 inch long flexible 1/4" drive extension that works well when doing this maintenance. But I prefer the 12" 1/4" inch drive wobble extension. And I agree with others, best method is to remove CPS & mounting screw together with cable connection intact. Once you get the drive extension & mounting screw out of the way, the cable connection is a piece of cake. (Note: I always worry about damaging the cable connector when I can't see exactly how it is locked in place. Expecially since these cars are approaching 15-20 years old! Doing that could make things difficult going forward.) Likewise, the reverse method is highly recommended for those that haven't had to do this maintenance.
