In box# 44 on the build sheet from my 70 442 it has the upper and lower paint codes, which I don't have a problem with but there is also an ST and W with a 10n6 under it. If the ST is stripe color I haven't been able to find it in the service manual or assembly manual or even the fisher body manual. The W is over to the right of the ST but the 10n6 is sort of below both of them. The upper and lower paint code is 28 which is Twilight Blue Metalic, there were three stripe colors available for that color Black, Light blue and White. With a medium blue interior(code 933) It may be the light blue. If you guys know where to find it listed I'd be a happy camper.

 

The paint codes for accent stripes can be found on the old Ditzler/PPG paint charts though there will be no help in determining exactly which color stripe may have originally been on your car.

You will find the codes in the lower left hand of the page in the above link.

Since it does not seem there is any striping code on the body plate I'd just select which of the possible colors that appeals to you. One thing is for certain if there is no reference on the vehicle no one can question the authenticity of your choice in a judging.
