Need help with caster #,s 66 Dart!!!

I'm not running an early A body. But, here's what I've done with my Duster. Using MagnumForce uppers, I was able to get 5.5 degrees positive caster and 1/2 degree neg. camber. It handles awesome and feels very stable. When in the midst of a turn I can let the wheel go and it returns to center (quickly). This on center feel is great for when the back of the car steps out, it makes it easier to gather control again. Only one problem with this much caster, it is a bit of a bear in the parking lot with manual steering. Arrrgggh!

With the stock uppers go with 1/2 degree neg. camber and as much positive caster as possible.

IMO, neg. caster will make the car twitchy at speed.
