I just had an SBT replacement midshaft housing rubber come unglued from housing and spit pieces of the new sbt rubber coupler out. I had about 2 hours on it - I think bad (SBT) parts. I may have a housing. Do you have anything for a FX-1? How much? DO you sell one complete, or do I need to press the bearings / shaft? I need a housing and coupler, taking it out tonight to see if anything else is bad.
