Those that have their reservations about grounding leads, clamps, or drilling and tapping a head could contact CH and order one of the newer systems with the different cap, eliminating the ground strap.
I've considered changing to the new caps but the old rubber boot system seems to work well so for. If I ever have to change a plug lead, I'd sure consider the metal cap. I sure like that system on other ignitions I own.
Ya know too, after I wrote what I did about tapping a hole, I could just see someone on here drilling a hole right into the combustion chamber ..... you know it will happen. Oh well, should make for interesting reading when they blast me for suggesting such a thing!!
