Heater control mounting hardware?

[knomadd]

I'm in need of some info on the mounting hardware for the heater or A/C controller. The PO removed everything heater related so I don't have any of the hardware or the controller. I had to purchase a new controller from ECE, but can't figure out where to get the hardware, or even what it is so I can go to the local hardware store and buy two screws or bolts...

The question I have is... What is the hardware used to connect the controller to the dash? Screws or Bolts? Any clips or should the controller be tapped? The controller isn't tapped now, so I'm not entirely sure what's supposed to hold it in place.

Any help would be GREATLY appreciated.
