When my 71 stage 1 was bought new, the dealer had applied the GSX stripes and rear spoiler. I confirmed this talking to the original owner, but should have put something in writing because I lost track of him and have no more information. So it was dealer installed, but it is certianly NOT a GSX. It was not factory installed. Someday when I go through this car again they will be removed and car will go back to original color. Kinda cool though. later Tim
