Sorry, I'm coming into this late, and I don't have all of the facts, but
possible reasons for a clutch to not disengage (brother...I've been there):
-clutch disc in backwards
-bad slave cylinder (they only cost $30 - maybe you should get a new one.
-Bad flex hose
-Air in the system (use a pressure bleeder!)
-Worn or missing pilot bushing. Everybody, including me once, misses this
one. A $4 part that will cause you grief. They don't wear much, but they can
fall out during a rebuild, or if your engine came out of an automatic
originally (if you dropped in a V8), it didn't have one, and needs one.
-Detritus in the pressure plate. I had a bolt fall down into mine once
during a clutch job, and my clutch wouldn't even *think* of disengaging.
If you feel comfortable doing it, send a boroscope up into the bell housing
(you may have to drill a hole - no worries, you can thread it and plug it
later). Watch to see if the plate moves as someone steps in the clutch.
Good luck,
