Greg,

I went to a hydrolic shop and had them make a custom hose for me.  The
size of the fitting that goes into the case is M10 X 1.  They should have
an adaptor that will allow you to go from the 1/8 npt to the M10 X 1.

I also bough this kit from egauge for my next setup, which will allow me
to mount the senders up in the engine compartment and out from under the
engine.  http://www.egauges.com/vdo_indA.asp?PN=150-856  You still need
the 1/8 NPT to M10 X 1  adaptor to make this kit work right.  BTW some
people just use the 1/8 npt right into the case without any problems
(except it messes up the threads in the case)

Also, regarding the sendor you have form the Cabriolet, you will only want
to use it for the pressure gauge.  The "idot light" will give you a false
reading if you use the Cabriolet sender for it because it is set to go off
at .5 bars.  All you need to do is use a "T" fitting and put the your
original oil pressure "idiot light" sender in it along with the sender
form the Cabriolet.  Then hook up the gauge to the Cariolet sender, and
your original "idiot light" wire to your original oil pressure sender.
