I made my own piece for the trunk lid and it's a challenge to get it to stay and not sag. Velcro wasn't strong enough. I used some of those plastic "rivits" and drilled some holes. The edge closest to the rear window doesn't have much room for error there. I've used some double sided gorilla tape, but in the heat of the summer it's iffy at best. Good luck. I wish someone still made one w/Turbcharged and power 6 embroidered on it.
