Never seen one like that...
If there are no markings on it denoting who made it, And I would think for something that involved there would be, Is there any chance a prior owner was good with fiberglass and customized a stock hardtop?

"The Jeep is a manly device. And a womanly device. An American device. It’s a fitting instrument to transport the free people of a free nation with the respect to which we are entitled and the dignity that we deserve. Okay, we’re a little crazy to have a Jeep for a daily driver. But if we go off our meds, we might wind up in a Prius"-P.J.O'rourke
