No I haven't but I knew as soon as I posted that there would be someone contradicting it .
Boy John,never knew you were that easily offended !!!!!
I'm not offended easily , my memory isn't as good as i thought it was I guess, I need to just sit back and and let others that have the answers do the talking, maybe I'll learn something. I have personally NEVER had a cap come off on any vehicle I have own that had a distributor cap.
I could have sworn I have seen an extra hole or 2 in the bottom of a distributor housing, the alum chrysler single point anyway ???
