why someone would get rid of the glove box sticker to replace with a new one. There is so little to authenticate a 68 z to begin with. Get a junkyard glove box door and keep the original for documentation. With the engine not right, it puts into question the protecto plate. what little I see of that, it does look convincing (but not seeing the blacked out portion means maybe the person is still alive on the car, which could be good). Probably would say that engine was blown years ago. But if that person said it is a real Z, then someone did good enough in that buy.
