This is an example of a gold interior, wrong stitching in the seats to what you are supposed to have, but the interior is similar to what yours would have looked like in color, except yours would have been much more stunning with the P6 trim, the picture of the dash pad is a bit off as it does not show the correct hue, the dash pad should be more close in color to the dash vents.............. You should be able to get a carpet in either light gold or camel color to match also.
Mopar made lighter color plastic from 1971 to 74 and color dyed it to what ever color they needed, it is a creamy beige color and they colored it to a gold color and other colors like butterscotch and others to match interiors.
I do not have the factory color codes in front of me
can't find them right now, but there are formulas for interior paint colors available too, not hard to get the correct hue when you have to color everything inside the car anyway, you would start with white door panels and color them, same with other plastics (under dash, kick panels, seat backs, A-pillars, etc, etc), order new seat covers from Legendary in the correct patterns and color, when you got a sample, send that to the guys who do the dash pads and get them to color match to the sample that Legendary send you.
easy as that.
In fact, i would send Aaron Beck $10 for him to do a chop of your car in B2 Blue with the P6 gold interior to see if the colors work together, i am thinking they would be fine, but it is $10 well spent to save you thousand in the long run buddy, that is just my
Not only would you only be spending money once on interior if you go gold, it will be correct if you ever get the urge later to restore the outside to original.........
Your call.
