As mentioned by Mike...make sure you place a spacer between each of the four adapter bracket mounts to back the fog back away from the opening trim. This is needed to allow you to aim the fogs down enough to be of use. For some reason, spacer were not mentioned or included in Diode's kit. They are in Baja's version. I used 1/8"+- thick nylon washers from Lowe's hardware...I can get an accurate description when I'm off work...
