Ok, here are the pictures. I have three of them, one of the OD of the threads, one of the OD of the valve inside, and one of the width of the opening for the valve retainer slots. Just in case someone wants to machine something and help a guy out. I'll pay, and then pass it around if anyone else needs it pro bono. Without further ado.....
The first picture is of the calipers measuring the outside diameter of the threads of the valve holder. 1.612" (Thats approximate. All of these measurements are! My brown and sharpe calipers were last calibrated in 2005, but they seem to be very accurate against bolts and sockets and things.)

Next pic is of the OD of the valve body itself. 1.155" by my caliper.

Third, the width of the opening of the slots in the valve retainers. 1.314".

The height measurement of the valve retainers from the deck of the head where the valve cap seals to the top is .35".
If anyone is thinking of making one, you would be awesome. Most places I have seen want 180 dollars or more for one of these tools. I can't go near that, as I am in the military and the government keeps us barely paid, but I can deal. I thought I could take my money set aside and fix this thing up, but I feel like I have screwed myself here. Shoulda got the campbell hausfeld vertical tank..........
