X2 ... so many possibilities ... no one right way
Your restoration appears to be extensive. You didn't mention your goals for this restoration. Will it be a numbers matching concours car or a factory correct driver..... It's your car and you should do what makes you the happiest. This is not (or shouldn't be) a business driven decision..... Of course there is residual value... usually only a fraction of the money into it.
If your doing it to sell it then that makes the decision easy. Do it the way the factory did it. If its for you, then do what makes you happy. If you worried about ultimate value, then do what ever you want that can be undone or swapped back. That includes stripes and interior...... We are living in privileged times where between the Internet and reproducers of parts for these cars, you have a lot of latitude which twenty years ago we could only wish for....i just bought the upper door skins in white for my 73 road runner...... Truly i must be dreaming.
The only standard thing about Mopars is how "non-standard" they all were.
As to the color you have there, it's not exceptionally rare or all that uncommon. You've got a great combo with a white interior and white stripes. Black stripe with black interior would also look good and really make it special...... Anything could have been special ordered back then.
My 340 73 RR was special ordered with a unique series of options.... It came with white stripes as did most of the roadrunners in the south. I'm sure there were regional differences in both colors and options sent to different dealers based on regional tastes. Found in Florida...there were a lot of light green cars.... To go with our harvest gold and avocado kitchens, walnut paneled rec rooms and gold anodized alum shower doors..... Yuk!
Ideally, the stripe looks best when matched to the interior. On light color cars the darker reads better because of the contrast. But with your new shiny un-faded paint, I'm sure it will read fine.
IMO.... Go with a white stripe and white interior with a black dash... That would be cool for me.... Question is what is cool for you????
good luck and keep us posted as to you progress! Nice to see someone doing a 73 right!
