I think that is 100% totally correct interior with the exception maybe of the green on the dash and console.
Look at the pic of the Plymouth int I posted above.
The lighting on the Mecum pics makes the shades of the paint look funny.
It also looks like the exterior tint isn't quite right either, but the upholstery looks right to me.
Right. The upholstery is accurate to me.
It’s all the green that I think is inaccurate.
According to all I’ve found, everything I have that’s green is supposed to be a gold, citron gold and or white.
I’m fairly certain they wouldn’t have put in white carpet in but I’m just guessing on what color the green components were originally.
The more I look, the more I think it was possibly all one color inside and that everything was a citron gold (no green or white)
According to some here and to information found at link below, there really isn’t any additional evidence suggesting more than one color was used for inside trim. Three digit code, one color interior trim.

Citron Vinyl Codes: P4Y, H4Y.
White Codes: P4W
My guess is that it never had any white interior parts because that would be a P4W TRM code and it’s a P4Y.
If true and if I wanted to correct the color I’d be replacing everything that’s green in citron gold. I kind of thought they would have been using at least two colors for interiors but maybe not.
