Alright people, since no one else wanted to share.
This is my PDP front mudflap install.
First I made a cardboard template to find where I wanted the flaps to sit. Once you find a good spot press hard on the cardboard where the bolts on the flare are and then drill out where the bolt imprint is. Then I installed the template to see if I liked the look and to make sure things were level. Once I liked that I put the template on the PDP flap and marked the holes. Drilled the holes with an 11/64 bit.
Then I mounted the flap to check fitment again then pulled it off and used the drilled flap as a template to drill the holes in the other flap.
Then I went HAM with Gorilla double sided all weather tape to add some strength to the mounting area and to keep the flap from rubbing the flares paint off If I decide to take the flaps off. Make sure both the flare and the flap are clean, I used rubbing alcohol. I also warmed up both mounting areas with a heat gun to make sure everything was dry and tacky.
With the 2 mounting screws and the Gorilla tape these flaps are going no where.
