Could be a pretty cool project,maybe make a 'lil red express Dodge truck out of it.
Bodied go karts were made popular in the mid seventies by Rupp with a Vega, Gremlin,Volare & a pick up truck after they had some success selling GM on their Monza karts in the late sixties. That could be a mid seventies Chevy step side. Manco took a stab at it also which it could also be.
