The nice thing about the lift-a-dots is that you can put different lengths of stud in strategic locations so that you could potentially use the tonneau and/or parcel shelf cover, and the soft top at the same time. It's hard to explain, but it would allow you to use a cover over the rear parcel shelf, and a soft top concurrently or a full tonneau and soft top at the same time (this might sound silly, but it helps in rainy climates when your car sits outside). I like 'em, but others may not. They are used on many classic English sports cars.
