A couple of years ago I replaced a 3 finger 'HAYS' type clutch in my '72 with a McLeod diaphragm type pressure plate and disk along with a new throwout bearing all from Steve Wilkinson. At the same time I also added an effort reduction kit from Bob Byars, this one has roller bearings and is a nice improvement from the stock one which uses bare metal as the bushing surface. The old clutch took a significant effort to use, I'd guess the force was somewhere in the 50 - 60 lb range. Not much fun in SoCal traffic. With the new diaphragm clutch and the kit I can now push the clutch pedal to the floor with my hand. I'd estimate the force required to be around 15 lbs, it's as light as a Honda clutch. I can't speak to any other brands but the McLeod diaphragm clutch from Wilkinson and the Byars effort reduction kit provided a significant improvement over the old 3 finger clutch in my car.
