I'm looking at 65-66 red/white color schemes and I'm trying to figure out how interior paint is determined. I've seen exterior red primary with just a white top have all red interior with white lower half dash and white door panels only. However when it's a deluxe red top/white mid body/red bottom I've seen the same interior as I mentioned and I'm seen it the opposite way ( all white with red trim.
Does anyone know if the red/white/red exterior had an option of both interiors?

 

I don't know if I would call it an option but there are variations (from plant to plant) in the "break line" placements, especially on the hood and across the cowl. In my experience, the lower dash matches the door panels, but not necessarily the exterior.

I found in the bumpsides if it was red over white the interior was red and vise Versa (not counting top color). But I've seen slicks with red over white and interior was white.
As I'm looking I'm trying to determine if I'm looking at a factory combo or a owner change.
