here's a nice solid original deck filler panel plenum box for all 1968 1969 1970 Dodge Chargers and Daytonas.  came from a rust free Charger parted years ago.  was taken apart on the spot welds.  this part was welded in on the front and back, factory only used seam sealer on each side.  remnants of sealer still on this part.  has surface rust staining because it wasn't a painted part, still some original factory blue paint remaining on the trunk opening side.  it's very solid and straight,  no rust, pitting  or other damage.   has the center bracket that connects to the back of the shelf tray.   Nice solid part for those who prefer original parts!
