I'd swear I called over there a couple of years ago and was told they didn't have any. (The same week that "specialists" were telling me "Oh, nobody sells 3/4" drive shafts any more.") It looks to me as if a PO used 1.5" hose on mine and just clamped the S&*T out of it until it deformed/conformed to the log tube. Well... it doesn't leak. At this time.
