found this duster

found this duster the other day. its in a chained-in fenced yard so I couldn't get great pics. looks like its a 73-76?? also it has a sunroof and the vinyl top is the snakeskin grain. Also two-tone paint, is this factory? its got some old 14" cragars on it and it looks like it might have been hit a little on the driver side front, its sitting kind of funny in its resting spot. bucket seats and automatic trans, but can't tell if its a v-8 or slant. rust present on lower quarters/rear wheelwells but the chrome is decent and none of the glass is broken. Anyone want to throw out a value I should offer if I can find the owner?
