And the wheelcovers of the puzzle car are those of the Devin, not the MCA Jetstar. So is the round rearview mirror.
They look like '70 AMC hubcaps.
13" Which also seems to check out, the car in the top pic seems to have smaller dia wheels and a wider track ( spacers to fit the 13" ?)
Headlights &rings seemto match Guido's pic as well.
I'm more interested in the mistery than a possible extra point.
Maybe MCA used a Devin pic as well as the bodyshape?
Here is a MCA pic that shows their logo a bit better.
