I'm not strong on the Cuda knowledge, but here goes..
#1, The hockey stripes were a '70 only thing. Your car might have had a build board style decal with the engine call out, which was a 71 only thing.
#2, and #3, The hood and roof should be body color, unless there was a vinyl roof.
#4, Argent silver, or body color.
My best guess here, but hopefully others will chime in.
