Ok so I originally bought 4 half moon mud flaps from Sharp truck for my 2017 GMC Sierra 1500. What I needed to purchase was the full sized rear. one phone call and I had the correct bracket and flap delivered. Great Customer service and will purchase again in the future.
The brackets had to modified due to the fact the holes that hold the brackets to the body of the truck were out of linement! Which made the mud flaps hang over the outside by over an inch. They looked nasty!
These Brackets were exactly as described. I used them to install my new Gatorback Flaps on my 2016 3500HD. They fit perfect and they gave the mud flaps a continuous solid surface mount to, making the installation trouble free.
