you won't be disappointed no matter the direction you take. the KYB's will ride rough, know that going in, the big 1.03's will exacerbate this. but you might find the ride acceptable, different people have different thresholds for things of that nature.
100% the stock bar back in.
another option, is to keep the stock .870's and up the front bar to something more substantial. this is what i'm doing on my 65 dart.
