I've got a set that I took off of my '70 in boxes on the shelf. They are ORIGINAL (i.e., right top pattern) and certainly worked when I took them off some years ago.
If your interested, let me know.

Does anyone have a recommendation on where to buy a good head lamp relay valve? I purchase one from corvette central about a year ago and rarely drive at night. When vacuum is applied to the yellow port and the green port is blocked it will not maintain vacuum pressure it leaks out of the bottom/filter. Too much money for the amount of times it has been used. Any recommendation would be appreciated.

I have been using 3-way solenoid air valves for over four years--they work perfect.
Why use cheap plastic when you can have stainless steel?!
All I did to install them was to buy the right size hose nipples at Home Depot (easy.)
Hook up the ground wire and attach the hot wires to the high/low beam wire with a relay:
This makes the operation automatic--the headlights come on and the 3-way valve energizes.
You can find 3-way 12vdc air valves on ebay all the time. $15-20.
You need two of them.

Could you post some more info on this?!!? I've already sent you a PM.
Both of my relays are leaking. I only have one hooked up right now and im losing about 6 PSI of total manifold vacuum from it. so I am VERY interested in the setup to fix this leak issue and also to elimate a bit of potential leaks

I can only afford the repro valves but seeing as how they are piece of junk to begin with I won't bother. So I've been researching converting to electric firebird motors for the headlamps eliminating the vacume system which would be my ideal solution but again, that is expensive and I have a wiper door to contend with. The 3 way solenoid method sounds good to me. Would love to see pics and more info on this. 
Something like this work also? (i know nothing about electricity)
