There are at least two different series of 10"Campys but to my knowlege they all have the same mounting dimensions. Panteras are well known for slowly collapsing the rear body structure; spot-welds slowly shear over time and things begin to move. A clue is if the rear tires have excess camber or if someone has added adjustable upper rear a-arms to compensate for the slow collapse.
Another thing that occasionally happens is a wrecked car is made into whats called a 'splitter'- parts of two (or more) cars welded together- inexpertly- to produce an externally good looking Pantera that forever has handling issues. Clues on these often have non-factory subframe einforcements under the floor.
Your car can be set up on a chassis jig and checked for out-of alignment areas, then corrected to factory specs, usually by welding. Monococques do not correct easily; be prepared. An experienced Pantera-specialty shop or even a cadre of old-time owners may be able to point out whatever problems are producing your tire rub. Good luck.
