True Tom, and I know Jack personally, and have done work for him. But what you are speaking of is cutting, moving, and re-welding the upper control arm to achieve a rearward upper spindle ball joint location creating more positive caster. Jack was/is famous for this along with bending hot or cold the spindle steering arm to correct "bump steer" .... he told me he could always pick up ET for folks in just that, plus the Caster fix and not even have to steer it anymore ... the car would drive itself ! In my Roadster I never moved the wheel! When I used to do "A"arm front suspensions back in the 80s I would just locate the upper control arm mounts about and inch back from center for built in Caster ... but you cannot do that on these old corvettes because they do not have a "ball joint" type contact at the upper and lower control arm ... they have an eye and pin connection which will not allow the dog bone to be laid back creating more positive spindle Caster. I know many, many cars were using modified front suspension components ... and it was not a big deal, and I don't know if it was within the written rule or not.
