I need to cut the rocker boxes (not panels) out of my blazer becuase one side is rusted pretty bad. Would a 6pt Cage like Greg's or Dylan's be enough to support the floor without the boxes. I have heard that some didn't even come with the support boxes. It looks like they would catch alot of muck thrown up by the front tires. I've been looking at the cage made by SmittyBuilt unless I can find someone locally to build me one. So do Ya'll think this will be sufficient or should I look at trying to find some new boxes?
