Hi all, Trying to buy some window weatherstrips or "cat whiskers" for my 71 gtx..The question is do I have an early or a late build? I have no idea how to tell.. Is it on the build sheet? Fender tag? I have no door sticker here--it is at my bodyshop.. I also have no idea when the "cutoff" date was.. TIA, Kevin
