I am just North of you in GA and have been around these cars from day one, and the 68 / 69 B-Bodies are our primary focus. For the trunk weatherstrip, there is basically two styles available. They are basically the same, except one has a lip which extends over the trunk gutter into the trunk pan area and has to be trimmed to fit properly. The more common style does not have a lip and simply glues to the trunk gutter. Starting at approximately 3 inches to the right of the lock mechanism, apply a small amount of 3M weatherstrip adhesive to the gutter. The correct cement was a brownish gold color and still is available at appliance repair shops that sells say refrigerator seals or buy the black at your favorite parts store. Then working in counter clockwise direction place the seal in place. Do not stretch the seal as you install it!! We use clothes pin approximately 4 inches apart to hold it in place for overnight. Work all the way around the gutter and trim to fit. The "V" portion should be to the outside of the trunk area. If you should need any other assistance, drop me a message as we specialize in the 68 to 69 B-Bodies.
