As far as I'm concerned in Europe the MD80 TR is only valid for DC-9-80 series apart from MD80 model (MD82,83,87 and 88) and M90 not sure about B717 would not put too much money on that.
here are a few pages that focus on MD80, try to google "MD80 International Forum" lots of forums and stuffs regarding DC9,MD80,MD90, 717 and so on.
cheers.
