Ok two questions, our trucks have rocker boxes since they have a full top. If I install a cage I can do away with these, how does that affect the floor? weaker? also the supports inside I need to replace, (already have all the replacements) the rocker panels and part of the floor are out, all of which will be replaced anyway, is it easier/better to pull the boxes to replace these or is there any kind of trick to replace all this sheetmetal at once? Like em big and topless Excuse me...Would you mind removing your import from under my chevy?
