What are the correct black colors for a '69 Z/28 for:

a) Black Rally Stripes? I assume Tuxedo Black (10), but I couldn't find any source that confirmed this.

b) Lower Rocker Panels for Camaro's with RS - in particular the gloss level?

Appreciate your inputs. I'm going to the paint supply shop in the next couple of days and want to make sure I pick-up the exact right blacks.
