Classic air

Im thinking about getting this kit too but im more concerned with how well the compressor mounts and lines up with the pulleys.
Also wondering if I can use the original under dash vent assembly that was used on AC cars instead of using their vents.

Yes you can use the factory under dash vent box. I used one on my installation instead of the Classic Air supplied vents. It took a little work but it does look way better.
