Sell that top and get a Bop Top...they're easy to install, require no holes or drilling into your body and fits like a glove. It will not flap at any speed, and you don't need any windwings. IMO its the cleanest looking top there is, it was the best investment I've made for my car so far...here's a pic taken by a buddy on a windy PA day at about 65 mph.
