HERE is some info about it. You have clutch drag issues...

Sounds like your typical spec clutch.

Adjust the clutch per jack's link ^^^

will find the problem my input shaft is leaking tranny fluid all over my clutch well look like i will be tearing into my transmission grate

Yay for leaky input shaft seals!

That sucks after having done the clutch already. I had the same thing happen. At least the transmissions in these cars don't weigh 400lbs and are relatively easy to get out.

Have you shimmed the pivot ball? That will make a big difference in clutch fork travel. Also if its at high rpm that you're having trouble shifting your clutch disk may be too heavy. They're hard to drive with but an unsprung 4 Puck is your best option for an easy to shift trans.

He really shouldn't need to shim the pivot ball unless the fork sits about halfway or towards the passenger side in the window on the housing. The fork position should be slightly towards the drivers side when the slave rod is touching the fork and touching the pressure plate fingers. If it's not then there could be something else wrong like the step height is wrong, disk thickness is too big, fork is bent, pivot ball or socket is worn, clutch fingers pulled in too far.
If step height is correct, disk thickness is good, pressure plate fingers angle slightly away from disk when installed, fork isn't bent, and the pivot ball isn't worn then you should consider shimming the pivot ball to get it in the correct position in the fork window.

So you're saying an unsprung puck clutch is the easiest on the transmission in regards to shifting?...
