Sam:

I usually try for 6 - 8 thou end float on the lay gear - less than 6 thou 
and it becomes very difficult to assemble.  Be sure to use the correct 
part - one with oil channels on both faces of the washer, otherwise 
lubrication may be insufficient and you'll have quicker wear.

The gear plungers that I believe that you refer to carry the same part 
number as the later side shift gearboxes, as well as the earlier top-shift 
box.  I suggest checking with BCS in Stockton CA, or with Precision 
Sportscar Services in Ontario, Canada, or possibly AH Spares in the UK. 
There should be used ones available.  If you really have no luck, I could 
probably come up with a pair for you here - lots of gearbox bits lying 
around these parts!

I used a very hard rubber sheet material to made a shift rail buffer and 
glued it securely in the bottom of the recess.  I've seen them come adrift 
in there and get all chewed up by the action of the rails, which may be 
worse than not having it installed in the first place.  Another lister has 
mentioned using a flooring material ( linoleum I think) - sounds like a good 
idea to me - the stuff'l be tougher than rubber.  Again, a chat on the 
'phone with David at BCS would be helpful - they may have the buffer 
available made of a suitable material that has worked for them.

    I have a few questions in regard to my BJ8 transmission.  Just
remember this is my first time that  I have been inside of one of these
things.

1.   One of my work shop manuals says that if the end float exceeds .012
on the layshaft
       unit,   the thrust washer  should be replaced.  Mine does, so I
will have to order a
       new one.  My question is, what is the minimum end float that I
should try to
       establish?

2.    There doesn't  seem to be a supplier for gear plungers(detent
plungers).  Springs
       are available, but not plungers.  Can I assume that you make your
own and if so
       how do you determine length and width?  I am missing the two
plungers that  fit on
       the main  shaft.
3.    I have read in the archives about the buffer pad that mounts in the
bell housing
       which keeps the shifters shafts from going to far, causing
problems with the
       sliding hub  balls.   Is there a supplier or again do you make
your own, if so what is
       the best material?

I would appreciate your input.  Thanks in advance.
