Don't be scared. I have a removable Cargo Master roof rack that attaches to brackets on my hardtop. It will hold about 100Lbs. Drilling through the hardtop isn't that big of a deal. I've had the rack 3 yrs and it still doesn't leak, squeek, move or damage the top in any way. You barely notice the brackets when the rack is off (it's off most of the time). Then it takes 2 minutes to bolt it on and haul gear offroad.
