1964-1966 Door panel question

[chevyrestoguy]

I have seen a few pictures of the door panels on the 64-66 trucks where the outer is painted Fawn Poly and the inner portion is painted white. Is this something that is part of the Custom Cab option?

I have also seen steering wheels painted white on trucks with fawn-painted insides. Is this stock? Maybe a Custom Cab feature as well?

The reason why I'm saying it is that my buddy has a '66 C-20 Camper Special with the Custom Cab option, and his door panels are all fawn, the steering wheel is fawn. Of course, his '66 has the dark fawn upper dash ('66 only).
