Which side? My drivers side gap is excellent, passenger side , not-so-much. Car's never been in an accident & I know that as I stripped & repainted twice! Factory rocker on pass side just is not straight. The gap is fine front/back & upper break line but the rocker was rolled incorrectly & is almost a 1/2" gap in the front and about 1/4" in the back. I guess it's not that big a deal because no one's ever noticed it, but me. I thought about welding in additional metal but said nah, that's the way it came.
