The only true CE parts are the bed side rails, the divider panel, the tailgate (although this is just a cut-down and modified clamshell from a suburban)the rear floorboards may be the same as a 1/2 ton panel. All other parts are either from a suburban or panel and common parts from pickups. The restored price can vary from around $18000 - to around $50,000. I have seen two on auction go for $43,600 and $18,800. Good luck.......g
