I don't use the positive stop, but don't worry about how high up the clutch pedal sits. It is just slightly above the brake pedal at rest.

My other main concern, aside that it full disengages, it that the spring on the clutch throwout arm pulls the throw-out bearing off the clutch fingers when its released. Mine spring hooks conveniently to a bolt hole in my scattershield.

I also removed the overcenter spring.
