One more question for you in additnion to the Ignitor III question above...is there any benefit in replacing the coil also? The one I have is a Mallory one that was no doubt nice as a performance part when it went on the car 20 years ago (before I got it and pulled it out of a junkyard...running, but out of a junkyard nonetheless)...but nice brand new repalcements are only $30 or $40 bucks...is that also worth replacing to get a real benefit? When I got a top end rebuild on the car about 15 years ago, they left this coil there presumably because it was working fine. But now is now and since the dual point is going away, would there be any benefit to chanigng out the coil also?

Thanks agian for all this info. Once I have my list of parts I'd like to put it up here for you to weigh in on it...measuere twice, cut once, that kind of thing! I really appreciate your input!
