Sorry, got rid of the instructions after I installed the flaps. Really easy to do. Just make sure you get the correct flaps as there are different ones depending on wheel size and if you have running boards. There's a few holes to drill, and a couple of screws/plastic quick bolts to install. I'll get the camera out and post a picture.
