advise for suspension setup for 67 dart

I never go negative on camber on a street car unless the suspension is designed for it and the owner wants it. People already put off rotating their tires. It's normal wear for tires to wear on the inside edge to begin with. Lack of rotation plus negative camber equals tires worn prematurely. I usually like to see .5 a degree positive camber. The difference will never be felt in handling, but will sure keep the tires wearing more evenly. As for caster, with manual steering you'll want a little less so that it steers easily when parking. Maybe 3* for manual and 4* plus for power. As for toe, I usually go for around .25*. I used to tell my customers to come back in about 1000 miles so I could see the wear pattern and readjust if necessary. You can spout numbers from a book all day long but they don't mean squat compared to what the tire wear is doing.
