I've searched the site for info on mud flaps but there's not that much (at least in terms of pics.) Biggest issue was where to mount the flaps and with what....it just wasn't that clear. There was some good info that helped me on my latest project, though, so I decided to post what I did and maybe it will be helpful.

I went to get the crew cab DRW inspected and this year was told I needed mud flaps. I pretty much knew this but have been avoiding it. My 75 F250 spits more rocks up and doesn't require them, but hey that's what DOT says I need on the dual rear wheel truck.

I was thinking about using some old floor mats for the mud flaps, but was advised they'd rip and be useless in no time. Good advice. I read on this forum advice that trucker (semi) flaps were cheap and could be cut to size. I took a chance and went to O'Reilly to see what they had, and in the back they had some pretty large generic--but heavy duty--flaps for about $11 each.

Got some 90 degree metal bar from ACE across the street, some extra 1/2 and 5/8 bolts and took a stab at it.

Basically I bolted one end of the bar to the frame--there was a pre-drilled hole already there--and then the other end to the metal flare on my truck. Cut the flaps to size, drilled holes at top, and attached to the bar.
