Negative camber

OK, sorry if already asked, but I seen alot about caster, but not much on camber. I have a 1970 dart guessing at some piont in its life it was in a mild fender bender? Passenger front tire is maxed out and still 2 inches or so of negative camber. Will tubular upper arms help? Or are then just caster? I bought offset bushings but only say 2 degrees so not worth installing and still be way in and have to get arms anyways.
