After we talked I went to Stevenson. They stock it. Apparently they split a lot. The new one is very pliable. What they did not have was an air filter.
My rig is ready for CM. I found a loose exhaust bolt (from manifold to downpipe, but everything else was shipshape. Thought I needed brakepads, but they were fine (no noticeable leaks but fluid is down, which made me think I needed to replace pads). Fresh oil (and they do have the big filters at Stevenson, but I got small - 1/2 the price).
