Exactly what meangreen said.
But I would add: Getting the Steeda Firewall Adjuster+Quick Release Quadrant+Adjustable cable was the best investment I made in my car.
I have about 3/4" of Play, then another 1.5" and I can shift. I love it like that, makes it easy to shift quicker. All and all it'll be about $100 max with shipping, and one of the best mods you can do to the car.
It IS a pain tho, getting up under the dash to change the quadrant.
The firewall adjuster lets you adjust it just by opening the hood, and on the 94/95s it sits just behind and to the right of the upper intake plenum. I still can't get over how much I love it. Shifting is 100x smoother, quicker, and I have more confidence in it now, because there isn't some piece of craptastic plastic pulling the cable.
Edit: One thing of note, from the people I've talked to the Double Hook Quadrant does not provide enough leverage to pull a big clutch well, if you plan on going with a better clutch, get the Quick Release one.
