    The '84-'85 should be very close...anything in particular you're looking for?

    well, i'm planning on putting together a brand new dash with new guages and everything. I wanted to position things a little differantly, and since I dont have A/C in the truck anymore, that whole climate control thing is kinda a waste. I thought it would be nice to have an on/off switch for the heat, and then just a dial to control the fan speed and leave it at that. I'm not sure if I could just redo the wiring on the existing heat system and fit it to my needs, or just buy a brand new heater system from like jc whitney and have fun with that.....

    I think as long as you didn't care about heat/defrost/cool, you could relocate the thing easily.

    Since the heat/cool/defrost settings on non AC vehicles are all mechanical though, (the cables) you are limited as to how far you can move the controller, unless you wanted to get real, real complex and use electric motors and solenoids to control the heater box doors/valves.

    Then again, if you left the (inner) AC box intact, most of that is vacuum controlled, and I think hot/cold is all that is controlled mechanically, which would somewhat simplify things.

    I removed the stock A/C-Heater system and replaced it with a non-A/C heater unit. It is much smaller and all the cables reached my new location just fine. Email if ya want some pics or info.
