Yes, I used the factory left front on right rear and RF to LR. Used the push pins that came with flaps. I found 9/32” bit for plastic wheel extension and 19/64” for the felt/plastic inner fender was tightest fit and still be able to push in lock pin. Taped in place to sharpie mark and drill...
Installed formed Ford factory front mud flaps on forward arch of rear tires. Very good match to raised profile of flap. Been on a few weeks now and really helping to keep step clean with my less than ideal choice of +0 wheels.
