Hey brother, I am having the same problem installing mine. If i take out the stiffner screws I can get most of the flange nuts on. However, i cannot get the stiffner screws back on and vise versa.I'm having one heck of a time installing my Rock Rails. I followed the instructions to at "T" and I'm a pretty mechanically savvy person. For those of you that have installed these, I'm having an issue getting the nuts on the 12 short allen head bolts that poke through the door sill. I have the 3 flag bolts loosely installed and the pinch weld bolts loosely installed. The problem is the flange on the rock rails is not sitting flush against the door jam. If the bolt threads were just a hair longer, it would be a non-issue. I have no idea why MOPAR wouldn't make the bolts a bit longer (there's plenty of clearance.
ANY help or suggestions would be helpful. I've tried a floor jack, hammer (causing too much damage), and using my legs as leverage while having a helper.......NO LUCK.
What a PITA job.
What did you end up doing to get the flange nuts on?
Thanks in advance.
