Duster expertise please!

Certainly not a factory paint job, that's an altered wheelbase drag-car?? Any insight on it's history at all? It may just be the pic perspective, but I've considered doing a conservative AWB for the street, paint codes aren't too difficult to find online.
LY6 would be Golden Haze, the base body color, the other color looks similar to the T5 Sienna for '74 cars. Cool find.
