I stumbled on that solution accidently.  My '84 had been plagued with
the no hot start problem for, literally, years.   I stripped a bolt on
the thermostat housing and ended up replacing it with a boneyard part.
It had the sensor in it.  After replacing the housing (& sensor), I
never had the problem again.

Glad it worked out.
