I purchased a 68 coupe without that piece. It is hard to find. I can purchase a new one, however, -------
I have two 68 Firebirds: 68 convertible ls2, auto 4L60E, red interior, white/black power top. I have owned since 1971. 2) 68 coupe, aqua/white tope. aqua interior, 350 4 speed. I am restoring this car and it will be for sale. Before paint or after.
