Default 69 rear axle sits too far towards driver side

HI All,

I have been trying to solve why my rear tire scrapes on inner fender lip on one side. It's on a mostly stock 69 GTO with 255/60/15 tires scrapes over deep dips only on drivers side. It has been shaving rubber off the sidewall and probably time to change the tires because of this.

I had replaced all the control arm bushing w polygraphite 20 years ago and everything looks good there. Axle seems to sit about 1/2 inch more towards the driver side of the car. Pass side has the clearance. The driver side also sat 1 inch lower but I adjusted that even with Spohn SP1 coilovers and adjustable shocks set to stiffness of what is tolerable but it still scrapes.

Car has boxed lower control arms with factory sway bar.

Any thoughts on how to balance out the rear axle so it sits evenly?
