Vent window locks? My 67 has vent window levers, no locks. So does my 69.
The 67's had that funky chrome plastic trim on the windshield and rear window, 68 and 69 had stainless steel, but it's easy enough to convert to the later setup with new window gaskets and the 68-69 stainless trim. Plus a few clips. I know because I converted mine back in the late eighties. Looks like this example has the later stainless trim.
The 67 doors had vents at the lower rear. My 69 doesn't and I'm not sure about 68, since I've never owned one. This one has the door vents.
I'm thinking this is actually a 67 Barracuda. Factory 383? Can't tell, but it certainly is not dressed out correctly. (Radiator is not correct, either.)
