I think you could make one pretty easily. Hot wire cut out the traced original shape from a lexan sheet, sand down edges, color-laser a waterslide decal on, drill holes for brackets. You could do it in less than 20 minutes and you'd have left-over plastic for future repairs/parts for the same price or less than buying a replacement. I've made parts using that process before, the first few were a tad rough, but smaller pieces are much easier and look great.
