No, there's no difference. If you look underneath you will see what i think is an reinforcement plate that leaves a 1/4" gap where water and crud collect and rust the fender from the inside out. It has openings on the corners but its not enough to keep em dry and clean, every time i wash my Jeep i put the nozzle up to the opening on the corner of reinforcement and blow water thru to keep it clean.

Anybody can take advice if it doesn't interfere with their plan.
