With rectangular headlights..... , It's either a '77. Or a '77 front clip. the 85mph speedometer makes me think it's a '77 all the way...........
It does look like the '77 wagon we had when I was a kid but wasn't '76 the first year for rectangular headlights?
'75 was still round-eyes. It's at least a '76...or some Frankenstein thing. '75/'76 I believe the parts would interchange, so you could go to rectangular headlights if you were so inclined.
The colors on that car make it look like some sort of emergency Red Cross vehicle or something ha ha.
