Awesome '65 Valiant/Barracuda hardtop wagon

There's something strange going on with that front valance. Looks like the outer parts of the opening are filled in and only the radiator area open.

Looks like standard-issue '64-'65 Barracuda front valence to me, see here The left and right extremities were blanked off on those because the park/turn lights were up in the grill rather than down there at the left and right edges of the valence cutout as in the '64-'65 Valiant. It's tough for me to level any criticism at this custom-built wagon because it's so skillfully done, but I might've been tempted to substitute a '63 Valiant valence (pics here and here) with the smaller, more faired-in central opening, and with the '63 park/turn lamp holes deleted or perhaps repurposed for fog lamps.

I wasn't aware that the Canadian 64's used the US Valiant dash.

Yep.

In '65 the Canadians had both Dart and Valiant based Valiants but used the Dart dash in all of them. I have a Canadian 65 Valiant 100 4-door myself. Very similar to the US version but it has the US '65 Dart dash and the "VALIANT" nose badge among other details.

I had a '65 Canadian Valiant Custom 200 -- this one, in fact. The Canadian situation in '65 was pretty complicated. Not just Valiant-shaped Valiants and Dart-shaped Valiants, but also US-sourced Valiants on account of some kind of a strike.
