excess positive camber 440 A body

Exackerry.
Too little toe makes the outer edges of the tires pull forward, this results in extreme positive camber.
Also, if the lower control arm pivot shafts have egged out their mounts in the K member, you may also have excessive camber either negative or positive. Get it in for an inspection with a reliable alignment shop. Make sure you find a place with a "seasoned" tech that is familiar with classic car suspension and steering. Lots of the young guys may mean well but are trained on what they see most: Late model cars that only have provisions to adjust the TOE. If a tech has no experience with the tricky nuances of a 1/4 turn of the cam bolts here and there, that guy will never be able to help you.
In the unusual case that everything is mechanically fine, you can add washers to fit between the spindle/knuckle and the lower ball joint. An 1/8"washer can add 2 degrees of NEG camber. Mancini Racing has them.
Excellent description,K.D! Watch out,some alignment schmucks,will toe out of spec,to make the quick buck. ( In order,to make up,for real work to be done...)....
