GG1 Racing green question.....

Well you see I'm confused. The car was supposedly repainted in 1986. The color looks very close to GG1. So checked the fender tag says GG1, but under hood and engine bay are a different green, I think probably F8, and it looks as if it wasn't repainted. Oh yes and the interior green on doors and door sills look as if they are close to F8. The dash is satin green, but not same shade as GG1, but more on the F8 side. I am assuming the car exterior was F8 from new, and changed to GG1 when repainted. But, I cannot understand the fender tag listing GG1? Regardless I am going with GG1, so I need correct green for dash??
