I have five booster assemblies left. PM if interested. I believe at least two came from '71-'72 Monte Carlo, so they am guessing those would not work for you.
They obviously don’t know **** then. I have seen a lot of right side up original car print Boosters. I am helping a friend right now with his Olds that has his original. Never been touched and it’s right side up. I had my GSX judged there several years ago and it was a non issue. Maybe they just deduct for Chinese specials with the sharp cut triangles?
