Another question for everyone.  The shift shaft seal is really leaking
on the trans now.  Have to top off the trans fluid every time I do an
oil change.  Guess it is time to get a seal but it seems that they are
hard to come by.  Does someone have the part number and what these
things run?  I have an 84GL with a 4 speed manual trans.  Also, are
there any special things that I need to know about replacing this seal
(like special tools or problems that might be encountered)?
