Greetings, I just acquired an older model Colorado XT 9 ft. pontoon that has frozen valves. It has never been inflated and is one that was created for Trout Unlimited. Unfortunately they no longer make this model with these older (white plastic) valves so now require I purchase an entirely new bladder and shell for both sides. I am unable to open the valves and had to put some WD 40 on the spring portion just to get it to start turning. If anyone has one of these older models or better yet a valve wrench or a spare valve please let me know. Any help most appreciated! Any help greatly appreciated!
