For a Milodon geardrive/super damper combo a special damper hub is requiered. $119! And don't under any circumstances buy a used damper. The ATIs may have to have all the bolt heads drilled out/off to disassemble. It might be worth asking if anti sieze can be put on the shoulders of the bolt heads before installation. I had to drill mine to dissassemble for rebuilding. I tried soaking them in wd40, penetrating oil, still broke multiple allen sockets.
