For what its worth.. I was NOT spending what they want for a set of mud flaps Call me cheap or whatever but I would rather spend that money someplace else. I made a set for my 2021- 2500 Bighorn using a stall mat from Tractor supply which was 29.99. The mats are big enough to make more than 4 mud flaps and are slightly over 1/2" thick. I used a jig saw with an aggressive wood blade along with a Multi tool to cut them out. It is a little tricky at first but you learn how to move the tools to get through it.
Later on I may add some anti sail weights to them just to give them that something extra. For what they are they work as intended and I have made them for my past few trucks now with no issues. I used a piece of clear poly carbonate I had laying around for a template. Just took out a factory screw from the liner of the wheel well, drilled a hole in the clear sheet, mounted the sheet to the liner with the screw I took out and traced the shape of the liner onto the clear sheet.. Once you do that it is all down hill from there! Cut out the shape and refit until your happy then transfer the template to the stall mat. Nice thing about the template is that you can just flip it over from one side to the other for passenger or driver side. If I remember correctly I looked up the flaps on line to see the dimensions for front and back and made mine just an inch or two longer. I can get dimensions if anyone is that interested. Here are some pics and YES, after I was done I made ALL of the hardware match. All of the original trim was left on the truck, I felt that it added to the stability of the flaps and didn't really see any advantage in removing it.
I may still have the template laying around...
