Looks like probably a rare 11/76 Papaya HX Sandman van BODY + VIN tags and chassis number (all match up). The ADR plate isn't the right one though, although all info needed is known so the mob that redoes them could conceivably make one for it. Or just build it up as a van and leave the ADR tag off. Also pretty rare in HX to have a 3.36 diff behind a 253 and 4spd. Normally they are 3.55.
