Andy,
You are quite right. The gauge that I bought needed something to seat
against. I tried to adapt some other type of fitting, but I discovered
that I had problems with leaks. If the temp sending unit is the same
on the '6 as the Spit, then the fitting should work.
As far as the dash goes, it was a straight-forward swap to replace the
original temp gauge with the dual gauge. The only other thing that caused
a problem was finding the right size fitting for the "T" fitting on the
oil pressure. There was a strange size fitting on the pipe that came
with the gauge.
A couple of caveats to anyone planning on installing a mechanical gauge
in their car. One, leave the piping loose. This applies to both oil and
coolant. The second caution is to be very careful with a mechanical temp
gauge. This is a closed system, the temperature is transmitted to the
gauge via the tube. If you break it, it is very expensive to repair.
