I installed those gauges on both the '85 5000s and the '88 Fox. Personally, I could 
do away without any gauge in the car except for the tach and the oil pressure. Oil 
pressure gauge is an absolute must-have, IMHO.

The most cost effective way is to get one from JCWhitney. My Fox wears the Oil 
Pressure, Oil Temperature and the Voltmeter from that cat. 

The neat thing is that Audi/VW use bores with 10x1mm threads for gauges. Imperial 
1/8 NPT is almost equal to 10x1mm and is conical (NPT has 27 threads per inch, so the 
step is 25.4/27, i.e. almost 1mm). I just screw in the 1/8 NPT brass adapter with 
Teflon tape until it jams and that's it. Don't get overzealous, though.
No leaks have been noticed so far on all the cars that I've ever done this way.

BTW, I always use a standard 1/8 NPT brass T (male-fem-fem). Male goes into the 
block, one fem takes the OEM idiot light switch (either the white one or the brown 
one, does not matter), the other fem takes the gauge sender. The computer function is 
retained and you aquire the analogue gauge at the same time.
