These cars were mostly speced for neg caster from the factory so getting any positive caster is a challenge. Doesn't matter which body style it is.

6 degrees positve caster is great for the high speed stability of a drag car but just not needed for a street application.

Camber is a tire wearing angle so if a sacrifice must be made keep camber in spec while mainting equal caster right to left with in at most a 1/2 degree.
