Air Condition Controls

[formula_raider]

I am trying to replace my stock (no/AC) Heater control panel with a new factory Heater control panel (with/AC). I thought it was just a bolt up situation, but the (2) large screws that go in from the bottom of the dash do not line up. They are too narrow, plus even if they did line up it look like the thickness and angle are incorrect. Is there a plate that connects to the AC control panel which inturn connect to the dash to line up the screws. I cant believe that the bottom of the dash and or holes are different for trucks that came with AC and those that didnt. If there is a plate; is it something I can get new from a vendor or will it be a junk yard part. Thanks for any help.
