Anybody know if K3 burnt orange was available on a 1970 Duster?

Been into B bodies for quite some time now, but recently picked up a 70 Duster for a father/son project. Last one of these I had was over 30 years ago in high school. We are wanting to paint it either K5 or K3, but want to verify that the lighter tone was available on an A-body in 1970. Cant seem to find a definite answer by searching the web.
