Changing strut rods

Did you have the car re-aligned? And have you changed the tires? And it's still pulling?

The measurement difference to the fender from the tire doesn't concern me. These cars left the factory with a tolerance of +/- 1/4" from the factory, and that's on the suspension. You could have a 1/2" difference from the fender to the tire side to side and still be in spec as far as the suspension and alignment are concerned. With that measurement you're taking into account body tolerances, tire tolerances, alignment tolerances, frame tolerances, ALL of it. Too many variables.

The strut rods, as long as they're the same length, aren't your problem. The only way your strut rods are causing a problem like that is if one of them is bent, or if they're different lengths. Otherwise, they're going to locate the LCA in the same place relative to the K frame. Maybe that's not the "right" spot, but its not going to cause a side to side difference.

The 19 year old tires scare the crap out of me. There's no way I'd drive a car on 19 year old tires at any significant speed for any significant distance. And if the tires are 19 years old, I'd guess they've sat for a long time as well. Could easily cause a pulling issue. The other issue that might be causing the location problem is the lower control arm bushings. If your tires are 19 years old, I'd bet that the LCA bushings have never been changed either. If one side is worn out, that could be your issue. If the suspension has never been rebuilt with new bushings, I'd start there. Its a lot more likely you've got worn out bushings, ball joints, tie rod ends etc, than a frame problem unless you suspect the car was hit.

What are your new alignment specs?
