Default STV Valve

Has anyone tried the replacement part for the STV valve on a 66 air conditioned coupe with 327/300 HP? My original STV valve is leaking and I have been unable to locate a new one. I have found a couple of places that sell a conversion replacement that changes the system to CCOT. I found a rebuild kit at Docrebuild that is supposed to fix the leak problem but the vacuum side of mine is also bad, the part that does the compensation for higher altitudes.

Mine did the same thing. I bought the conversion kit and pumped up with R12. WORKS GREAT blows 34 degress inside the car.

Does the conversion kit hook up like the STV or do you have to do some special plumbing?

I have a new Delco replacement valve that I had on my 67 briefly. I replaced it with one of the conversion valves since I will probably convert to 134. It is gathering dust on the work bench. If you are interested, drop me an email.

All the conversion kit is a block off plate and a new switch. It will not be hooked up to vaccum line anymore. It has a switch to mount. With my conversion kit I made it look original.

P.S. 66 has a STV valve and 67 has a POV valve. THEY ARE DIFFERENT.

Try corvgreg (supporting vendor). I bought a used POA for my 67 from him and was very satisfied with the quality/price. http://www.gregsclassicauto.com
