Well, since there wasn't such a thing as Candy Apple Red from the factory I'm guessing you mean Cardinal Red, color code T. Need to know what the original color of your interior was/is and then I can look the pinstripe color up for you.
Jeff -- The reason I didn't list my "source" for this information is that unfortunately I don't know when or where I got it; so, it may not be true. We need to find someone who has an original showroom album of paint and upholstery as I believe it would list the pinstripe offerings.
I checked both the original paint/upholstery book and dealer facts album that I have and neither lists paint stripe colors/combinations. I don't think I they are missing any pages, but who knows? My '69 paint/upholstery book is not quite as complete as the ones I have for '67 and '68, which do list the color/trim/stripe combinations.
