paint color w/o build sheet or fender tag?

I have a duster i picked up a couple years ago.
from the vin I can tell it was a 340 4bbl car with special pricing.
but is there any way to tell what color it was?
the fender tag and rear seal are Long gone unfortunetly.
it had a console ( floor brakets and auto shift linkage hole are there ).
has a ralley dash the interior is gone and its been messed with and painted at least twice. just want to make sure its not something rare or odd before i finish what the last guy started and turn it into my racecar.
plus if it was a odd or nea color i might repaint it that way.

Thanks!
