Low vacuum - should I ditch my vacuum advance distributor?

Out of Curiosity = Why not use an early Electronic OEM Distributor and
recurve it or even just take out heavy spring and bend tab out for more tension
on the light one? That is what I have been doing for 50 years. The used mopar ones
are a dime a dozen and easy to find.

It is easy to add or subtract how much the weight move so you can adjust how much
advance is in them.
