Well, make me an offer and we'll see what happens. I don't know if anyone sells these things anymore? Atleast I have never seen any for sale on ebay or elsewhere.
I put a manual operated valve in my vert a few years ago. Far from stock and everytime I wanted to control the heat, I needed to pop up the hood first. Not really practical, but better than no control at all.
This NOS valve needs vacuum and there were vacuum lines broken in my car somewhere under the dash, so... Never installed it.
