I'll plead ignorance, since they are about the same era I assumed that
VW would do some parts sharing.

The ones I'm thinking of were black (for gauge) or blue (for ECU) and
were mounted in a plastic flange where the coolant hose connected to
the head.  Held in with a little spring clip and sealed with an
O-ring.

If they are not troublesome in Vanagons, then I'm glad to hear it.
