What model Formula? Does if have a curved top, or just square? I busted mine in my 242 by not having it latched when I jumped a cruiser wake. It was flat. I went to a plastics place, and had them cut a pieced to size, then I drilled the holes and installed it. You can run a bottle torch along the edges, to round them off (bullnose we call it in the tile trade

). They would have made the whole thing, but I wanted to save money. My 302 has a curved door, and the top at the curve is busted off. It had been siliconed on, but came off.
