I think Twisted6 had your answer, somewhat, regarding pedal play. I believe what he was asking was how much play to you have in the clutch pedal at the top, not at the bottom.
There should be some play at the top of the clutch pedal when you initially press the clutch pedal in. There should not be immediately disengagement. There should be some freeplay travel - perhaps 2 or 3 inches, as I have with mine.
With your vehicle off make sure you can press the pedal with your hand and get some travel before you encounter some resistance. If not then an adjustment is necessary so that you do not prematurely wear your clutch. That's the first thing to do.
Second thing is to check the fork travel distance. Bending the fork may solve your problem, if it's one of the later thin metal forks. If it's the older cast iron type fork then all bets are off.
The newer throw-out bearings are "taller" than the older OEM style. So you won't get as much travel if you use your original clutch fork. You have to compensate for this by either finding a newer fork or making mods to your old one.
One or more of these has to be what's causing your problem, assuming no parts are defective.
