| I see this has sparked alot of debate and questions. I am not a big fan of holes in the car myself, but options for mounting points that actually gave the cooler purpose and value added, were slim to none. There were issues with the mufflers being in the way in almost every other good spot. Only other good spot was on the driver side corner. However, this increased the amount of hose running under the car and in the system as a whole. With the location that I chose, everything is minimized. Also, the cooler is still up higher from the ground than the diff itself is. The pics may be misleading on this fact. As for the holes, I drilled them through....used rubberized undercoating on both top and bottom.....expanding foam sealant in the spare well around the bolts.....and the spacers between the cooler and the body are full of RTV silicone. The spacers I used are actually head bolt washers (I think). They are thick and have a bigger ID than the bolts mounting the cooler, so the silicone is sealing the entire bolt to the washer and the car. I take every precaution to assist this car in living as long as possible. Almost 220K now and only one rust spot under the rear hatch seal! W00T! More details on all of the R&D will be in the write-up
