If you can find a vacuum advance unit that:
1: Still works.
2: Is compatible with the carbs.
3: Fits on the distributor.
by all means install it. Good luck, heh, heh, heh!!
Actually, the traditional vacuum advance is mainly
an economy measure, you get more efficiency at part throttle
(cruising conditions) because of the extra advance.
As long as you adjust the timing right, it should run OK without
any vacuum advance.
