Ooops, you didn't mention that :-). Timing specs that you quote (sticker)
are for a stock vehicle with a stock ignition system. You are right in
that you have a vacuum advance unit. If the unit has a vacuum advance then
you disconnect and plug the line when you do the dynamic timing. In either
case though, what I said regarding the advance for general engine ignition
timing is still correct-
