If the fenders youre using arent original to your car, this might be a familiar sight. Although everything else lines up, theres a gap at the rocker panel. Most body shops would call this goodbut not on a high-caliber job from the Hot Rod Haus. For Cross, this means carefully measuring the gap, pulling the fender back off the car (first taking note of the shims used), and welding additional metal on the rocker panel to tighten the gap. Thats something wed certainly leave to the pros, and it reinforces the importance of pre-fitting panels before final bodywork and painting.
