Sheet metal

Let me see if I understand correctly.

The 70-71 Duster & 71 Demon rear side markers are the same?
But the ‘71 Demon front side marker is a one year only? What is the difference?

So this means I need to get the front from a ‘71 Demon?

Do you know if there are any other A Body models that would have the same front side markers as the ‘71 Demon?

I’m hopking to get the rears from a ‘70 4 door Valiant. They should be the same. Correct?

Thank you!
