We measured from the front to a point where the metal was solid. We’ll be replacing the front 34″ of this inner rocker, which is over half of its length. For this repair, we’ll significantly destabilize the right side so we’ve made sure that our bracing is extra-secure. We’ll also be measuring as we weld to make sure the body doesn’t shift and affect the door gaps.
After carefully measuring and cutting, we welded the new inner sill section in place so we can continue with our other repairs.
