The Bestop Replace-a-top is the only replacement top featuring American fabric specially constructed to stretch for easy installation then return to its original shape for tautness. The Replace-a-top also features factory-spec velcro, thread, webbing, and door seals. Plus oversized zippers, DOT approved windows. The Replace-a-top consists of fabric only and fit only factory-original hardware. Replacement top only fits on factory OEM hardware. The doors must have black plastic door handles and a Jeep label sewn into the top. This top will work on steel or fiberglass bodies. If you are installing this onto a fiberglass body you will need to purchase snap kit part # 93002. Tops go on like the factory top. You must use factory door frame and cut off the old skin. The new door skins stretch over old frames and attach with Velcro and snaps and reuse your original door handles.
