So, you're by-pssing the heater?
I would think you'd want all the gauges to match, so you need to let me know what you want to do.
The original owner of my blue car installed one with a wire wound capillary.

He broke it and replaced it with one with the black plastic sleathed one, which is still in the car and is fine. I can let that one go because I found an nos wire wound one (cost me a fortune). The SW I have is traditional black and white face, chrome bezel, 270deg. sweep. (I think it goes to 240).
