Hello I was wondering if anyone has done a retrofit of fender flares for a truck without them I have some that I’ll be getting from a 2021 truck that had them from the factory I was wondering if anyone has done something like this I have a 2020 tradesman and have heard the oem ones have clips he says they were removed and that it’ll bolt right up do they just go into the holes where the liners go those same holes and do they actually hold on tight like they won’t flap when driving. Do I need to get any special trim pieces since mine didn’t come with them from factory like the plastic pieces that run along the bottom of the truck.
