<VV> Cylinder head temperature switch

[Jim Simpson]

Other than the mounting threads, what is the difference between the
"regular" Corvair cylinder head temperature switch and the Corsa
(140/turbo) head temp switch?  I seem to recall claims that they operated
at different temperatures (the Corsa version being higher), but I can't
seem to find anywhere that's documented.

Anyone know for sure and where to find it?
