I finally got around to trimming for my 33s. Cut the bottom of the rocker flush with the next layer of sheet metal. Then marked a straight line (curved to the body) to the trailing edge of the rocker panel. cut it back and voila... no more bent sheet metal.
i cut perpedicular outward from the end of the 2nd layer of sheet metal.
i used a piece of tape to make this "straight" cut line.
post cut and non-matching paint
The offending piece
Final result with tire back on.
Will update with results after next wheeling trip.
