I just replaced the water temp switch (below the oil filter) in my 79 SA with a stock replacement. I was wondering if I bought an aftermarket electric water temp gauge if it would be compatible with the temp switch I just installed? Thanks.

Agree ^^ tried it in mine and it didnt work. if your gonna go with an electric gauge by one that comes with the sensor, i personally think they work alot better. I use glowshift in my 85 and they work great! fairly cheap aswell..

Thanks for the quick replies. So assuming I bought one with a sensor and wanted to use it in the stock location (rather than drilling and tapping), do you know what the stock thread size is on my 79 so I can make sure I get the right adapter?

off the top of my head i do not know i can look when i get to the house, but to he honish i would change the spot depending on how built your 7 is. my sensor was at the bottom of the radiator and by the time the car is warm the gauge isnt reading over 100 so i relocated my to the water pump neck and it gets great readings.

The motor is completely stock...just a RB Holley and RB header.

ok, you could just use the stock location then.

if you've removed the stuff on top of the engine, you can use the spot in the back of the water pump housing.
