The rear fender flares and polyurethane side skirts were test-fit on the car. | 
Stainless 8/32 x 3/4 bolts hold the side skirt to the rear fender opening. | 
A 1/8" gap was determined to be necessary for the door caps to clear the side skirt. Eighth-inch masonite strips were cut to shape and evenly spaced out to give a symmetrical gap underneath the door cap. |
A black Sharpie marker was used to mark locations on the door cap. These notations act as alignment points so that as the cap is taken on and off the car to do bodywork, I can keep the position correct. These marks can be easily removed with rubbing alcohol. | 
More 8/32 nut rivets were injected into the door cap to secure it to the car. | 
Nut rivets were also injected into the front fender to act as a foundation for securing the fiberglass fender flare to the metal fender. |
The body kit manufacturer cut a 1/16" groove where they thought the gas flap door was supposed to be. This is just a cut in the primer and I was responsible for cutting this door out. This predetermined placement was checked to ensure that a gas pump handle would be able to proceed through the opening into the car's gas flap. | 
The fiberglass fender flares were bolted to the metal OEM fender. | 
The rear fiberglass fender flare was prepared for cutting the gas filler door opening. |
