Am in need of air valves for 87 tsw01060b687 15.4 ft inflatable boat. Cant find any info. Have written the company without any luck. Im in Montana USA. Also if you have an owners manual or brochure. Am trying to help an elderly friend replace the valves as some leak. Also what is the difference between a trs and a tsw model in the vin number. Thanks for any help.
