When I put the thermostat in Mr. Hyde I ran into the special gasket problem
and created a short jumper wire with large inner diameter connectors to
clear the attachment bolts. The wire itself is very short and just loops
around the gasket on the bottom side of the thermostat housing. I have
never had any leaks or connection problems. A short piece of thin brass
with the proper size holes on each end might be a neater solution and work
just as well if you put some anti-seize on to prevent oxidation.
All the correct gasket has is a small piece of brass pushed through the
gasket material and folded over. It is only about 1/8" wide if I remember
correctly. If the connection corrodes you could loose the temp gauge.

If this is the SRL (i.e. U20), more likely there's no ground between
the thermostat block (where the sensor screws in) and the engine
head. The 'proper' gasket between these two parts has a metal staple
in it, which provides electrical connectivity thru the insulating gasket.
Oftentimes, a PO will use the wrong gasket (one without the staple),
or intentionally remove the staple from the gasket, not realizing why
it was put there.
