Adjustable Master.....
Adjustable Master..... I have a spec II and I have the shim in already that they gave me but when I have the cluthc pedalall the way down at a light I can tell that it isn't fully disengaed, the car rolls slightly. Also does it when I have the tranny in reverse and the clutch all the way down, and I mean DOWN, the car rolls until I put my foot on the break. It acts like it only likes the damndest little bit from being disenged. This also cause a problem with putting it in to gear coming from nuetral. So should I put in another shim or get an adjustable master cylinder.

Almost sounds like there's still air in the hydraulics.
You only need an adjustable master if there's upward pressure on the pedal when the pedal is released (if the pedal is pushing against the stop at the top). Ideally, you want the pedal *resting* against the stop, but not *pushing* against the stop.
If the master is pushing against the stop, you'll have the problem of the clutch not engaging all the way (it slips). Your problem sounds like the opposite - it's not releasing all the way.
With the shim in there, you've got a pre-load on the slave to pressure plate interface. So in theory, it should disengage the clutch earlier.
The only thing left (that I see) would be air in the hydraulics, not allowing the slave to fully travel to disengage the clutch.

welcome to the club 
Just look for my post about a week or two ago ("A damn good question"). I'd give you the link but I'm at work and this computer's slow as hell. Anyways, I had the same problem and it's now fixed.
