If anyone is having trouble finding aftermarket sponson parts, I found a way to make them. I just recently made an inner bracket for a Beach house GSX sponson. I took the broken piece to a company called TAP plastics in Nor Cal, there were able to cut me the exact piece for a lot less then buying a new set, the only draw back is that all they had in stock was a white material. I had to drill all the holes and install the threaded nuts. The piece is identical to the Beach House parts. If any one needs a replacement I will be more then happy to help.
