Help with Painting 69 Dart dash/dashpad

I know the B7 color's been talked about here before, and my car was repainted in the late 70's. After removing parts recently that were masked over for that repaint by whoever, this B7 color more represents what my car looks like on the inner top portion of the inner door. Especially behind the heater blower motor on the firewall.img_0504-jpg.jpg
