If you need the cabs color code, look on the plate on the firewall, it's usually there. If not, ask the peeps mentioned below, they will have a chart.
For the coach, as you may have the only surviving example left on the planet, I suggest that you drive it to an auto paint
supply store and have them bring their portable spectrometer out to the coach and read the color, then they can custom mix paint
to match the now faded color of your stripes. They can usually make it up in either a regular can or a spray can, or both.
And, as the stripes may be decals, ask them what paint you should use.
