Sorry Andy,I am also interested in this top for my GTX 1. Who does the fitting? I live in Colorado.
I was on vacation when this question was posted. Steve Hemstock does it currently. He is out of WI., his number is 715-702-2727. But if you give him a call he can help you with any questions. Also Shadowman can do the install. He is out of No. California. PM him if desired.
And there is the GT Guys, see below.
