What I ended up doing in the end (after trying everything I could
think of and that was suggested) was getting a speed bleeder and
combined that with the mityvac to suck air out of the bleeder port.
I cranked up the pressure to 15 psi, slightly opened the bleed port,
and slowly cycled the pedal with half strokes. The clutch is very
firm right now and staying that way. I believe it is bled well to
this point.

I just drove it around for half an hour and I only experienced a tough
shift one time. It was when I heard the rattling metal like sound
(see above post about that). As soon as it happened I pushed on the
pedal and it did not engage as early in the pedal stroke and the
tranny was stuck in gear. I let off the clutch, waited a couple of
seconds, and pressed the clutch again and it was firm again and it
shifted just fine. I think I am changing my mind on where the rattle
is. I believe it is where the clutch line and bleeder line exit the
bell housing. Its hard to stick your head by the pedals when you are
driving and the clutch wont release, but I tried and it sounds like it
is originating from that area. I tightened the hose down along the
firewall and of course it does not rattle nearly the same now. There
was a rubber grommet of some sort where the hoses exited the housing
when I tore it down, and that was the one part I was missing when I
put it back together. I forgot I was missing it during reassembly
because I was tackling getting the cross member bolted back up and
forgot to look for it when I was done. Do you think the lines
rattling there could be causing clutch issues, or something is going
wrong in the system and the line rattling is just an end result of
that? The clutch is very predictable, and will not release, when that
noise occurs but I don't know if not having the rubber piece in there
is a culprit. Ideas?

Also, I am a little worried about the tranny fluid I am using right
now. I am using Mobil 1 synthetic which I believe has additives in it
that are harmful to synchros, but the manual called for a GL5 based
fluid and that is one the part store had. I am thinking about
switching it out after doing seom reading, but I do not know what to
switch to. There are a variety of opinions out there. Any
suggestions on that?

Thanks guys for the help.
