My truck is a 2020 Ford F350 DRW 4x4. Sharp Truck made it easy to buy the correct GatorBack flaps and brackets, and the pre-slotting saved allot of time (worth $40). If your truck is like mine, the 12x23 cut flaps for the front, and 21x24 rectangle for the back are the correct size. I didn't want to spend the extra money for the bracket kit, but I am very glad I did. I can't say enough good things about the brackets. They were indeed custom for my truck, fit perfectly, and contained every nut, bolt, screw, and washer that you need. You need these brackets for a straight and secure installation. I can't imagine mounting the 12 pound (each) rear flaps without them. Unless you are an old pro at installing these things, the installation video is a must to complement the written instructions. While the written was great at identifying the parts, the video helped you determine which part went on which side, and how to position the part. While these GatorBack flaps and brackets were expensive, I have no doubt they will last for many years. Very high quality and heavy duty. The hard part of the installation was aligning the rear mud flaps with the holes in the brackets. Some of the holes end up with 5 layers; 3 bracket pieces, the wheel well liner, and the mud flap. The key is using a fine point punch to assist perfect alignment as you install the 10 bolts that hold on each rear flap. All the components align and bolt together for exceptional strength. Having said all this, they look great too!
I had a set of heavy rubber flaps 12X18 sitting around the shop and these brackets did the trick, I'm used to bolting flaps to a piece of angle iron bolted to the truck frame pretty simple right? I still don't understand the why with all the parts and with the oddly placed holes and the slotted piece that goes inside the fender on the tire side, It seems kinda complicated but I'm not an engineer, all in all, pretty solid set up once I figured it out, the instructions recommended a specific video on utube but it said this video has been removed, I found one that was ford branded and it worked along with the instructions.
