It looks like 3 pieces on the car, but it is actually all one piece.

1. Pull off old piece, and clean out the grooves with a brush, and use a razor to clean the windshield area
2. Put a line of silicone in the gap. Some people use "goop"?
3. Starting with one of the corners, carefully insert the new weatherstrip and push it forward to fit into the groove.
4. Use a plastic trim removal tool, or really anything that has a thin rigid end, but will not cut rubber. Place into the groove of the new weatherstrip (on sides of windshield) and press it apart, thereby locking it into position. This will make more sense when you're actually doing it
5. Drink a beer
