Clearview makes a good product.
I have one on my 99' Interstate and it has been great.
This guy in St. Augustine, FL that will be my source for windshields from now on though.
He makes a top quality product and will customize it just about any way that you want and his prices are very reasonable.

This guy is really good to work with, and pretty much if you can think it, he can make it.
Not knocking Clearview at all, just throwing out an alternative is all.
