A three-foot extension, a 7/16" "Universal" socket, and five minutes' work with a Dremel and a cut-off wheel makes the job MUCH easier for me - since I don't have to actually remove the bolts anymore. Just loosen them up and gently pull on the wiring, and it comes right up. Put the new one in place, rest a long screwdriver on it, and tighten the bolts. Takes 10 minutes, anymore.
If you haven't found a picture of how I notch the CPS mounting bracket, let me know - and I'll see if I can dig it up again. I know I've posted it here a couple times - it's not the best picture, but it gets the point across.
