If you do AC, then you need to insulate your Rig. A Bronco is nothing more than a Bread box, insulate the roof, floor, inside the doors, quarter panels, etc. Or else it will be nothing more than a cold breeze on your knees.
Having stated that, I used BCB AC kit, with the Explorer AC compressor. If I had to do it again, I would recommend the Sanden compressor they sell with their mounting adapter. Not all the hoses in the kit worked for me, I had a few made locally, returned the ones I didn't use. Dirt Donk now owns this Bronco, so hopefully he will chime in. My one negative is that it did not blow out the heat like the factory heater box did with the Ch*vy motor and squirrel cage.
