Negative camber

As stated, pics would help. If your ride height is set way too low, then no amount of adjustment will help you either. If you are set at the correct ride height or close to it, and your upper arms are maxed out and you STILL have 2" of negative camber (top of tire is further towards vehicle than bottom of tire) then there is going to be some glaringly obvious damage somewhere up there. It's difficult to guess what can be happening on a car that is 50+ years old
