The idea about mounting neons is to put them in a place where the tubes have little to no flexing. Otherwise they break. Ok, on the sides, if you look underneath, there's a lip that comes down a little. You mount them on the other side of that right next to it. On the back, there's a little shelf up under a big rectangle thing. Mount the tube in that shelf. On the front, just mount it anywhere on that bottom part. Be sure not to mount it to your front bumper though. If you have any more questions, just post and I'll catch it.
