Hydraulic clutch?

I have a 68 Plymouth Barracuda with an A-833 4 speed. My wife wants to drive this car but cant push the clutch very well. Is thier a hydraulic clutch kit for this car? I looked all over but am unable to finde one. I dont really want to alter the stock clutch but she will not let me spend any more $$$ on the car. Please please help me keep my car going.
