The single rail J type overdrive requires a special shifter cover and
linkage that raises the shifter lever and rail (rod) over the overdrive
unit.  The only components it has in common with the standard shifter
are the socket the shifter lever goes into.  You can use a 4 speed shift
lever, but it isn't hollow for running the overdrive switch wire up to
the shifter knob.  

I had never tried using the earlier 3 rail shifter cover and linkage on
the single rail gearbox, so I cannot say with certainty it will or will
not work.  I strongly suspect it will not though.  The three rail
shifter socketed into three distinct rails that moved the synchro units.
 The single rail uses but one, controlling the shifting through more
complex internal gates.

Without an overdrive shifter cover and linkage, you really can't make
the overdrive unit work.

My questions are:
1.  Does the overdrive transmission take something special, or
2.  Does it take the same shift mechanism as a single rail, (I think
this is
the exposed rod and cover plate)
3.  Can one of the top mounted remotes ( I think from a three rail
transmission) workl with this transmission.
