87 4k CSQ tranny bad at 67k miles?

I thought tires too, (always optimistic :) ) so I took the good tires off
of the fine running and driving '86 and put them on the vibrating '87, which
had crappy tires on it at the time. Regrettably, no change.
I think what I'll do next is disconnect the CV joints at the transmission
and see if the noise changes. If not, it's either the tranny or the clutch
(dunno how the clutch could howl like that) and either way the tranny has to
come out so I can have a look at the clutch before commiting to a $1k tranny
Thanks for the help!
