Green interior

I have a 69 barracuda that is triple green. The exterior is F5, with a green vinyl roof, and the interior (inner door frames) is F8. And the dash/column is Bayou green. I had a hard time finding the correct paint formulas as is normal for interior colors. I found that the interior upper door frames were not the typical Ivy green that you see on your exterior but a somewhat brighter green (they are original paint). The point of my explanation is that I ended up using a PPG fleet color book to pick a close color to the original. I found that it was easier than trying to find a formula for the interior color and turned out spot on. Just a suggestion in case your supply store has an issue finding the right formula for your code.
