Well, this is another myth about spare tops. We have this cloth top, too. It does not hold well hat highway speeds. Have had it try to blow off a few times. The front is held by velcro. Not really good when going 70 mph.
So I would not really recommend getting one.
From previous posts, you can see we have tried them all. The best tops are the t-tops that copme with the vette or a new pair that fit well.
We had a set of the cloth tops, for our 79. I must not have had it on right one night, it flew off at about 60 mph. Then it got run over by the car behind me. In my opinion it was a big waste of money. :W:
