318 electronic distributor

ok, so here is my dilemma. I have a 95 magnum 318 in my valiant.
currently running a MSD dist & 6AL box. I have persistent miss that wont go away.
pretty sure its Ignition related as I can occasionally even catch it on my timing light.
I have changed the plugs, wires, cap & rotor with Zero change. not sure if it is in the box or distributor ( both were purchased used ). I am looking to swap or replace both.
I know they are Both overkill for what I need. The car is just a cruiser and I want something reliable and affordable that I can easily get parts for.
should I just get a stock remain distributor and run a gm hei module?
or are the skip white? distributors decent? or the proform?

if possible I would like to have HEI terminals on the cap ( I did see summit sells a cap for the stock dist that has these )

Thanks!
