Caster could be changed by shimming the control arms with washers. On the 7000 Shelby's, all the control arms were mounted in double shear, and the fronts had 3/8" worth of adjustment in them. Camber on an original could only be adjusted by changing the length of the spring. Not real practical, and when the springs settle, the camber changes.

The lack of adjustability is why the fliptop and a few comp 289's used the heim jointed control arms.
