it is supposed to be on that bottom corner, that is so when you drop the top that part can bend with the top and flex. It should be free and not anchored to the trim also, about 3-6 inches or 2nd or 3rd screw depending on the brand of the early A ,darts are a deeper cut that valiants) tucks inside to allow for free movement and so it doesn't tear in that area. that's going to look NICE on that car.
