Re: 6.7 bumper swap
I have both a 2004 and 2016 F350 in my driveway. I have plans to use my 2004's Road Armor bumper and modify it to fit my 2016, but not until next summer. Will need to adjust the grille drop, the frame horn reinforcing bracket and end to line up with the fender arch. Comparing with a tape measure, the 16 bumper's main bolts line up with the 04's. The difference is the 2004's grill is narrower so there will be a gap where the drop begins. Both have the same depth drop. I didn't look at the brackets that keep the ends from flapping.
