More pics with port layout required. What ports does it have, what's the schematic for it, what's it off?
Take the solenoid coil off and see if it has some numbers on the barrel.
The dual ported plate is similar, but probably wrong orientation. Can you get on to the aftermarket equipment supplier?

I contacted a Daman dealer. They said it was probably a proprietary block made for someone specific. I asked her what made it specific and what was the next closest one they offered... so far no response back.
I can probably find one similar elsewhere but want to exhaust this option first before i look for another because of its mounting.
a Daman AD05SPSB8S has the ports like you want. #8 SAE ports on opposing faces. The 8P would have 1/2" NPT ports.
