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.
I have just the right shop for this work they specialize in classics and the owner who is 80 still manages the shop with his son. I need to put tires on this beast to move it. The outer edges are on steel belts and most shops want to do alignment after tires are purchased. Doesn't sound like the tire size will matter too much. Thanks, I am sure there is some part of this suspension we will find needs replaced or repaired.
