you could probably tune the mechanical advance to your liking for the set up. it'll take some trial and error, and a spring kit and/or limiter plate/cam but all that stuff is under the rotor and easy to do.
but if you want vacuum adv just get a stock mopar electronic distributor, you don't need the whole kit. contact
@halifaxhops he can set you up with one that's already dialed in for your needs.
here's the wiring for the 6AL to stock EI
