You've nailed it...
...but why should that be a surprise???
It's the Australian-designed VH Valiant (in this case, the 'Ranger' variant) with the Hemi 265 HP under the hood. The keen-eyed enthusiast (Ben?) will recall that the VH coupe was offered only in a 'mock soft-top' design, usually with a contrasting coloured vinyl-covered sheetmetal roof. Necessity is the mother of Invention, however, and Junior bought himself an angle-grinder...
Well spotted Art.
Cheers,
