I agree with JDsDream that you most likely have the original factory top. (technically not a MOPAR top, since MOPAR is their after-sales division, but that's getting picky).
You can go to this page
and try and match your hardware to the right picture. That'll give you a better idea of what you have.
IF you have the factory hardware, and need replacement fabric, you can get the Bestop Replace-A-Top. It uses your hardware, but gives you new fabric and windows.
If you have an aftermarket frame, you need to make sure exactly what it is. If it's a Supertop, then you can still get replacement skins.
If you already had a Replace-A-Top, it would have the Bestop Yellow B on the window, like RBloodhounds Jeep does.
