Looking for a bow filler cushion for our 2017 S211. I was wondering if the 2018 or newer S211 filler cushions were the same size (was there a layout or hull change between these years?)? We contacted our local dealer and they were told by the factory that they only go back 5 years on those and were out of luck. Or if anyone has one laying around they want to sell let me know?? My final option is to find the material (anyone know what brand material they use?) and have an upholstery shop make one for us. Thx in advance for any info/help
