Here is a basic install using the Shark Attack II in the factory antenna hole. This is a basic install that takes roughly 20 min. and should get you some points at the shows. First is to mount the antenna in the factory hole. Here is a shot of the inside of the quarter panel. The fastening nut is finger tight so the base is able to be adjusted. Here is what the install looks like so far. It is on straight but the angle is all wrong!!! This is fixed by "clocking". The antenna is rotated in its hole to bring it to the correct angle.
