I recently installed this universal under dash unit in my 73. I have a t-shift and C4. With the way I have it mounted, no 4L, but I don't use it, so no loss there. It is a/c only, like the old school Mustang or Bronco dealer installed units. With the kit, I had to remove my stock hood latch assembly and use hood pins to make room for the Condenser in front of the radiator. Again, no too big a deal, I would rather drive comfortably in the summer, than retain the stock hood latch. The kit comes with a small electric fan, which would have been nice to use, but I didn't have room for it. I am using the Wild Horses rigid fan off the water pump, and our Staggered 4 core radiator w/ trans cooler. I had to make a bracket to mount the compressor. I ended up mounting it on the passenger side, above the alternator. I still run a 2 belt setup, the compressor runs with the alternator belt. Belt tension is crucial here. Other than that, the kit comes with enough hose, fittings, and clamps where I was able to reasonably plumb it myself.
So, how does it work? Engine heat?
Yesterday it was about 103 degrees here in CA. I drove comfortably home from work with the windows up and cool as a cucumber! Typically my 302 runs about 195 degrees or so. In 103 heat, a/c full blast, I run about 210-220. Warm but steady. My only complaint, or criticism is it doesn't blow crazy hard. If you like the cold air blowing on your face like a new vehicle with dash mounted vents, you won't get that. It is more of an ambient cool, unless you lean closer to it, rather than kicked back in the seat. BUT, for $500, it is hard to beat, in my opinion.
