Five years ago I purchase an old grill for a 69-70 Shelby. It came off of a donner Shelby. Now I took it out to see if the snake and trim ring fasteners were the same as the ones on my car. They were not. The old grill had small flat metal rectangulars that you push pins through. Also I’m not certain that the ones on my car are correct neither.There, I have little washers and nuts holding the trim ring. The fasteners holding the snake look more legit. Would appreciate your help in sorting this out. Thanks, Carm.
