Thanks Bob and everyone else who has replied with a wealth of info. I will
do some reading on all of the info and check to see what specific cam
advance I have on the early model. Sounds like the consensus is keep the
early model with the vacuum advance.

There are specific dizzies for specific years. The differences are:
1. early cars had vac advance and retard, laster cars have retard only
2. the amount of mechanical advance varies as a function of year.
The physical mounting is the case on all years.
You can put that later unit in, but you have to plug the vac. advance
vacuum line or you'll have a fairly large vac. leak in your system.
