I also noticed the bolts supplied are 1/4'' too short for the compressor mounting brackets. They DO fit, but not properly, the bolts are threaded about 3/4 into the nut. I ended up taking one of the bolts to a hardware store and bought some that were a 1/4'' longer, perfect fit! I tried multiple different ways to use the supplied hardware, maybe were both missing something? Other than that, it cools pretty well. Side note... after I installed a new aluminum radiator and sealed the side gaps between the a/c condenser and the radiator everything cooled MUCH better.
