The 2-105 and 2-150 had the AC condenser core on the back of the cab. I'm not sure if the 2-85 was out before they moved the core up front. In some ways, it would be easier to use one of those as you wouldn't have to figure out a way to mount the core in front of the radiator. You'd only have to mount the compressor on the engine and run the hoses.

I would personally look for one off a late 2-85 or 2-105, and find a way to mount the core up front. You would not be able to use the 2-88 or 2-110 cab without modification, as those had the modular cabs with the console shifter. Last time I was at O'Brien County Implement (2004) they had some cabs in their salvage yard.
