I am hoping someone can tell me what this hardtop came off of for I just received it with a 1968 Alpine. I don't think it is correct but do not know what it goes to? It seems to be made out of fiberglass and does not have the pins on the rear to mount it buy? The gentlemen I got it from said it fits the car , but I would really like to have to correct top for my car. Thanks in advance, neveridle
