Chuck:
Additionally, once you get the top fitted, you might want to do what I did and cut a small (about 1") circle of adhesive backed velcro pile (not the hook) and attach it to the inside of the rear window where the bolt on the diagonal leg of the roll bar touches the rear window. I was concerned about the relatively sharp edges of the bolt damaging the clear material or cutting through it.
Using the small diameter circle it's completely hidden from the driver's view by the diagonal leg.
