Hi,

I sent the note below a little over a week ago and want to thank the folks 
who replied.  The general advice was to go through the mechanical and 
hydraulics to make sure that all was in the best possible shape.  I've done 
this and replaced the
1. clutch master and clevis pin
2. clutch slave with long through slave from BPNW
3. pushrod and clevis pin for the slave cylinder
4. flexible hose with new stainless hose

The clevis pin for the slave cylinder pushrod is now in the middle hole, as 
it should be.  Shifting into first and 2nd seems to work fine now.

However, this hasn't solved all of the problems ...

I had taken the car on a 250 mile round trip on the interstate and there 
hadn't been any previous problems.  The occasional crunching going into 1st 
and 2nd started on the way back.  The other thing that started - and I 
assumed would be fixed at the same time - is that downshifting into 2nd or 
into 1st acts like the synchros aren't working at all.  Upshifting to 2nd 
doesn't seem to exhibit the problem of crunching and grinding.

While I was under the car after the trip checking the clutch slave, I 
checked the transmission oil and it was *low* by about a 1qt.  I'm using 
50w motor oil with the transmission/J-type OD.  I'm concerned that either 
the synchros or one of the bushings or bearings are shot.  Anybody have any 
advice?

Thanks in advance!
