Details seemed quite well done. The written instructions were not that helpful. Basically, you need to figure out which part goes where. You can match the outline of the wing to each piece, and knowing the finished side is facing backwards, you can match the large holes to the plastic rivets. There are 8 screws in the kit but 4 holes in the front and 2 holes in the back so you will be short but you cannot use the bottom holes as there is nothing solid to screw on and if you don't remove those rear tires you don't have easy access to the inner vents. The rear rivets also no longer fit - they are too short. I have longer ones, but I'd also like to secure them with a screw, but I'll have to come up with that. Aesthetically they look great. I need to clarify if they offer any protection against dirt/dirt/water running off the tires.
