Rarest A-body on Fabo?

Not rare rare, but quite rare
1 of 1300 Valiant charger R/Ts
1 of 5 with H51 Aircon
1 of 1 with a mistake in the option codes chalked/rusted into the underside of the dash frame. Tag /body number/engine number match but the Aussie equivelent of build sheet, the chalk markings, does not in one important area
it says E37 but it aint E37 can't be E37 with H51 No space.
