You need a header that matches your top. They are NOT interchangeable*
If you're getting a Replace-A-Top, which is all the fabric, but you reuse your factory hardware, then you need a factory windshield header.
If you're getting a Supertop then it will come with a header. As will most (but not all) our competitors tops.
Pick the top you want and like. THEN worry about the header.
*Some people will argue that you can make a drill-in header work. And some people even like that style better. These are the same people who like welding on their Jeeps, who spend hours arguing over rear anti-sway bars, and who strengthen their rear axles with cross braced tubing for a fun weekend project. We can ignore these people, even if their name is Jerry B.
