'69 C10 Stepside white paint?

[data89]

Okay, I've searched the pertinent forums for this and also checked tcpglobal paint chips with no luck.
All I can find for the white is one color called white! Yet the interior cab white is an obvious gray toned white while the cowel and exterior cab top is an obvious white (or not, hard to tell with the overpainting of turquoise). I can find nowhere the name/number for the interior gray toned white. I would like to paint the original whites. Can anyone supply some info on this? The build sheet is too damaged to read and the spid doesn't list colors.
