If it has negative camber for sure the lower bushings are toast. Don't mess around. New lowers, offset uppers and good strut rod bushings. I took my strut rods and cut the threaded ends off. Turn them down the ends a touch on the lathe and connect with moly tubing. Make them 3/8" shorter. Pulls the lower arm forward slightly increasing caster. Cheap, strong, light, easy. This combined with offset upper bushings (forward location) will usually get acceptable alignment results, done many.
