I decided to temporarily set the step/rocker in place and get the rough fit done. It took some cutting and grinding at the junction where the rocker meets the cab corner. Im happy with it at this point. Need to set the door to make any final adjustments before i finish welding the outer cab corner.
The step comes back out while i replace the front door pillar. I have all the patch panels. Another challenge for sure. I hope the passenger side goes a tad faster.
