There have been a bunch of bad synchro rings running around.  AFAIK no one
has been able to pin-point what the problem is, they just don't work very
well in some gearboxes.

However, did you check the force required to move the shift hub ?  That
force is what operates the synchros, and I believe it's fairly critical.
The springs seem to get weak with heat and age and then the synchros don't
work as well.

If it's any consolation, I have the same problem on the Stag gearbox I just
went through.  I did check the shift hub force, but since 3/4 was within
range (barely) I left it alone.  1/2 was below the range, so I added shims
(which took it to the top of the range) and now 1/2 is a bit notchy but
never grinds even when I crowd 2nd.
