67 only stuff

The 67 windshield gasket uses a combination lock strip/trim piece to fasten it in. Very few if any vendors are making the lock strip aftermarket, and I don't believe anyone is remaking the gasket right now, so if it's pretty crispy or leaky you'd have a hard time replacing it with a 67 piece. You can use a 68/69 gasket fine, they're the same size, you just won't have any trim on your windshield unless you also add the clips to hold it used on the later models (those little spring clips that are so prone to rusting out, lol).
