Temperature Controlled Vacuum Valve

I am looking for the entire temperature controlled vacuum valve that goes in the heater hoses on my 351c 2V. Does anyone have one or know where to find it?

NPD has reproductions.

That is a PVS valve used to control the vacuum from your carb EGR port to the EGR valve. The valve's intended function was to aid in warm-up driveability. Lol...some never made it past the trash can when the new owner and car got home. They can be identified by color code or engineering #. The most common valve for a '73 351C Mustang is D3TZ-9D473-A which could be blue or have a plain top. ID numbers changed several times through the '80s. You can use valves marked D3TE-AA, A1A, A2A, D5DE-B1A, D5ZE-A2A, D7ZE-A1A, A2A, E1SE-A1A, A2A, AND 77TF-A1A. I have found these on E-Bay by searching for "D3TZ-9D473-A".
