Agreed, and thanks for the offer. At home, I would check against a thermometer; 
however, I'm on the road (Squamish, Canada) and need to improvise. I put a new 
thermostat in--in a motel parking lot--and get exactly the same reading (160 
with two 180deg thermostats) so at this point I'm convinced the gauge is 
reading 20deg low. Before I left, I pulled the gauge out a half-inch or so to 
replace the O-ring. I think I might have stretched or bent something, but IIRC 
the gauge was reading low before. Also, the gauge indicates 192deg when the 
engine is turned off, and it used to indicate 212deg exactly. The speedometers 
are largely calibrated by moving the needle, might try same on the temp gauge. 

Off topic, but I bought a set of wiper blades from Moss and installed before I 
left knowing we'd likely get rain (we did). Unfortunately, the blades drag so 
badly the wiper motor couldn't move them. Installed some old ones and motor 
works fine (the Moss blades--the rubber part--are about a half-inch wide and 
don't seem appropriate). Anybody else experience this phenomenon? Having a hard 
time finding replacement blades; thinking of trying 'Trico Classic,' but not 
sure if they'll fit the wiper arm (which, FWIW, appears to be a 5mm). Got an 
Anco brand 10" blade--unfortunately the store only had one--and it works great 
(with an adapter for the arm) but it's black!

You should check the temp with an infrared gun (Harbor Freight for 30 or so 
bucks). Aim at the thermostat housing. Then if you still feel it is off, remove 
the sensor and see if there is crud around it. I cannot think of anything that 
would cause the needle to have moved. If you don't want to get an infrared, I 
can bring one at the next Healey event we both attend. Let me know where you 
are headed and I'll let you know if I'm going.
