Ok, thicko question now - how do the roofs stay open? I opened it the other day and it blew shut once I was over about 30mph - I looked and decided that the rubber strap with the slit in it would logically hook over the little plastic hook in front of the hole in the roof - there's one strap and one hook per sunroof but the rubber strap will nowhere near reach the plastic hook - what am I doing wrong here? Spring is springing and I want to cruise in my babe-magnet with the roof(s) open!
