Trim code translation, please

'73 Road Runner.....need to know what to call Carpet Colour Y-7 and Trim Code colours C-2 and Y-4. Will one of these codes be for the headliner?
Thanks...

No but this will tell you what color the carpet and headliner are:

73 Satellite accent colors

Your interior code is C2Y4 (Gold). It's toward the bottom in the first column

Thanks, 69CoronetRT. It actually did give the Headliner Colour. This is the information I was looking for.
