I bought some OEM mudflaps from the local Dodge dealer and installed them today. What a PITA !! It was certainly an adventure. Why in the world after all these years of the Challenger, Dodge can't get the holes lined up properly is beyond me. For those of you contemplating the install be aware of a few things: to do it right you have to remove all four wheels. The rear flap holes do not line up at all. The install took a lot longer than I would have expected. I didn't have a plastic rivet installer so plan on having to buy one of those as well. I'm sure a lot of you guys will say it was easy, but for those of us that do not have a lift or the necessary tools it sucked. The install is done and they look great, but Dodge needs to figure out how to get the holes lined up and make this install easier.
