I love the Duffs 4" flares but want to make sure the opening is large enough. I plan on moving them as far forward and back to stretch my wheelbase with 3 link front and 4 link rear and run 38s. If anyone has a pic of 37-40" tires with these flares it would be greatly appreciated. Would also like pics of them held up against stock fenders to get an idea how much cutting these will afford me. Thanks in advance!
