Thanks Kelly,

I just placed an order with Mazdatrix this morning for the clutch parts
I need.  I bought their Centerforce I pressure plate and clutch disk,
new pilot bearing (didn't know it wasn't a bushing), alignment tool,
and a few other pieces I thought I might need.  Maybe the transmission
is OK.

On a related subject, the gear shift is located about 10-12 inches back
with a round shaft connecting to the shifting mechanism inside the
transmission.  Would it be difficult, or even possible to shorten that
shaft?  I think the stock location will be too far back in the Alpine.
