caster issue help!

[MAbbate22]

I recently bought a 99 carrera from an auction which had some evidence of a light off road excursion. After driving the car i decided to get it aligned because the steering wheel would not track back to straight after turning. The alignment needed some adjusting but the caster in the front was around 6 degrees on both sides which i think is a whole degree shy. I changed out both the front struts because they were a little bent thinking this would be the fix but it wasnt. I also took a few measurement on the car while it was on the lift and do not believe the frame is bent. Anyone have any ideas? Is there any way to adjust the caster, the shop who did the alignment said it was not adjustable. If this is true is there any crash bolts or any other options??? Please help i would really like to enjoy this car but cant with this current set up!!

Thanks any idea on what could be broken or bent?

If your caster is off, I would take a hard look at

*thrust arm

*thrust arm mount (on my 986, you have to remove the plastic wheel line to be able to see it both front and rear)

*bushing in the control arm to which the thrust arm attaches

*the top strut mount to be sure previous owner didn't do something funky like reposition the hole or put in some weird mount

*and suspension sub frame (not sure if you are talking front or rear, and am unsure on the 996, but on my 986S, we were able to re-center the rear suspension subframe)
