I never said these were drill less... and these brackets are FAR cheaper than Duraflaps (not knocking on Duraflap, they make an excellent product, just simply saying they are not for this truck).
After that commercial break folks, here is a picture of the brackets as promised.
Here's a shot of one of the brackets rotated 90 degrees, along with my intended use mudflaps (I have a CAT thing
You will need a 1/4" self tapper, some ingenuity, and whatever hardware you desire to mount through your mudflap. Here's the top mount location
I'm debating whether to leave the bracket hang like this, and mount my mudflap to it and the bed, or find a way to brace it to the bedskin, and use it as some structural reinforcement as well as a mount.
*NOTE* this image makes it look like the bracket is very close to the leaf spring, I'd like to point out it is not close AT ALL. There is plenty of a gap between the bracket and the springs for you off road folks to flex the $#!T out of those springs and not have to worry about your mudflaps getting rubbed on by the springs.
Anyway, my thought at first was that I could definitely make a bracket like this at home, with an oxy acetylene torch, some 1/8" steel and a little motivation (which I definitely could) But for $5.00 each, I would probably have that much into the fuel it would take to get to the nearest welding shop with metal for sale. I will post pictures of the bracket mounted, and with the mudflap on it after I finish it up!
