I too pulled a section of the dash pad under the trim at the instrument cluster.
in order to figure out what color it was. The dash is in bad shape but that section cleaned up fine.
As for the carpet, I can't guarantee it's original but everything else on the car seems to original (and rough). I pulled a section from under the dash near the gas pedal and the loops aren't crushed but the color sure looks like ivy gold. The areas that are exposed seem to be much lighter. Maybe I'll see what I find under the seats.
I thought it should be a light brown which why I was confused when everything looked green.
