Recently got a jeep. It is a 91. I was driving it on the freeway when the soft top came off. When that happened it broke part of the frame work for the soft top. There are 4 plastic circle pieces on the end of the bows that slide into rails on the interior of the jeep. One of those broke. Does anyone know where I can possibly get that part instead of buying a whole new hardwear set? I would prefer to not pay 250 bucks just to get that part.
