Who's idea for the 68' Hemi Dart

If you look at the "mule car" closely you'll see the seats are fibreglass mounted on tube steel, the offset block for the MC was made of wood & IIRC the backseat was gone, anticipating the finished cars would have a divider/rollcage installed when completed. The Authentication Guide has a list of parts that were used in these cars to make 'em & unfortunately alot (most) of those parts are unavailible. The good news though was that if you're creeative & diligent enough alot of the parts were "baseline" pieces for other vehicles.
