Thanks for the directions to the 400 series and up and larger conventional cab fenders.I just suspect they are just so large,they would look out of place on the truck I am beginning to work on.I am still searching and looking for a way to get some additional width without growing the entire fender and spreading the distance of the headlights.A flare maybe?Some fabrication is in store,and a lot of mock-up,if there aren't any examples out there.
