1996 Ford Mustang Clutch for Schwarzenegger

Hello,
I have purchased a 1996 Mustang. Its a V6 with 5 speed manual transmission. It drives good, runs good. The engine was rebuilt prior to my purchasing it. My only complaint is it seems the clutch was specially install for the Governator himself. I swear after a couple of months of driving it my left leg is larger than the right.

Is this normal, is there any adjustments that can be made? How would I go about doing it. Someone mentioned that it may have a hydrolic clutch instead of cables. When I look under the dash at the pedals I see no cables. I do see a large plastic arm that moves with the clutch, and large spring around the bar the clutch pivots around.

Thanks for any help.
