Hi Alex! Haven't spoken with you in ages! I didn't realize your Pantera had the type of damage that required "pulling" to straighten it out. If I were in your position and required this type of work on my Pantera, I'd take a week off from work, rent, borrow or steal a trailer, and take the car to Dennis Quella (Pantera Performance) just outside of Denver. He's successfully repaired some VERY badly damaged Pantera's.
If you want to stay local, I'd call John Riken at Burrard Autostrasse Collision in Vancouver (604-731-4123). Tell him I sent you. I was in his shop a few years ago, when he was in the middle of straightening a crash damaged Ferrari Boxer. He said the frame on that particular car was very easy to pull.
Either way, call Dennis first (303-660-9897). At the very least, he'll give you good advice.
P.S. Don't even think about painting your Pantera any other color than the original bronze metallic!!!
