Will the under dash A/C unit from a Jeep Wrangler fit under the dash of an early Bronco. I've seen them on Ebay and they look like they may fit.

 

see if you can get dimensions then check your clearance. If it will mount under your dash then you should be able to hook it up. May have to fabricate some compressor brackets but that should be fairly easy. Good luck.

 

The sale # 7987661635 looks like it would be the most promising. Although I would get some measurements of the space between the lower portion of the dash and the floor board. The unit looks like it may be a little deep for the EB. My a/c uhit has the motors mounted behind it so there is not anything hanging down in front below the vents. That piece may also interfere with your t case shifter. Not sure about the others how they would work as the motors and other parts mount above the vent areas which would put them up inside teh dash area.
