A simple fix would be to purchase 1 or 1 1/2 inch diameter aluminum round stock (eBay) and cut to the length you want. Drill and tap each end to the thread size needed and mount. Obviously you will nee to attach the threaded piece to the seat first. Paint if desired. The fact that the seat has the machine screws sticking out makes it even easier. SIMPLE fix (especially with drill press and mitre saw) and probably less weight than the overpriced, out of stock bracket Juiced Bikes sells.
