These are so sweet, the install was a little tedious, but anything worth while takes time. I had to cut the bolts holding the origianl lights off, I then drilled holes thru the front sheet metal to use my new mounting screws. The old lights were 4" wide and 3" tall and the new lights were 5 1/2" wide and 3" tall. since the original outboard screw was below center I was able to drill a hole above it centered as far to the outer hood as possible and then drill the other hole about on inch past where the inboard bolt had been. The Po had installed a eye bolt in the center of the grille, so I kept it, I also used the back of it for my negative ground. I also need small plastic bushings about 3/4" between the grille and the lights to create a tight bond
