I have a rear stear tandem bike I can't I.D. It had a 1956 Hawaii licence on it. It almost looks like a Colson. The frame is Female in front, and Male in Back. The bike shops in Hawaii can't I.D. the threads on the axles. they are not standard, or metric. Even the front fork threads are strange.One guy said the threads are a little more angled than normal. The skip tooth rear coaster brake band, or bar has the letters WND stamped into it. The rear steer control rods have no linkadge, just 1 rod on each side with a loop on each end. The loop goes on a post on each side of the fork. The bike had rotten GoodYear Thunderbolt GT 26x2.125 tires.I need new seats, fenders, handle bars, etc., but I want to find the right parts of the no name Tandem. I can't even find axle nuts because they are not Standard, or Metric. Please!!! I need your help.
