T-Birds had them, and so does my bronco II. I don't like them. They feel different sometimes, add fluid over time, maybe even having to bleed the system, to me its just another thing to wory about. What kind of clutch cable is installed in the car? I bet you its not a ford one, aftermarket cables suck. I made the mistake and installed one in my GT. WAY stiffer...By your complaint you must be very weak, or have a aftermarket cable, which i think its the problem.
Hope that helps.
