OK. Only 6 days for delivery via USPS from San Juan PR. Nice.
Top is specific to 3B, fits windshield channel perfectly, with one snap on either side at the top of the windshield side frame. The length would be just perfect for a vertical rollbar. I have an old Morris bar that is rounded left-to-right (for rolling) and tips backwards more than normal ones. As such the top just comes to the back edge of my rollbar, rather than a few inches over. Straps for footman loops are pretty good, with a quick release buckle so you only ever adjust them once. For taughtness, again I suffer from the rounded rollbar which I expected. There is a dart in the fabric that would accommodate the squarer roll bars but makes the top a bit saggy on my jeep. Fabric quality is hard to describe - different from the old vinyl canvas tops, but very sturdy and tough. I would call it an upgrade over the old ones. You do need footman loops in rear, windshield channel and two male snaps already on your jeep. They do not come with the top.
For now, I will carry it on longer trips in case of hitting some rain. Perhaps I will change rollbars when I put the new body on.
