Is my interior correct?

I've got a 66 Monaco and the interior makeover is coming up soon. I want everything original in there.

My cars got a red interior everywhere except the steering wheel and seats, they're black. I dont think I've seen a combo like that before on the site, just full reds.

So my question is: Is this an original option, or has some one messed with it and it was originally full red?

I love a full red interior, but will keep it as is if that's how it came.
