The only other infomation I have is that this was originally a 7 or 8 speed bike - back in '98. So that might explain the rub past the 7 cog.
Your triple probably also has a 42 ring rather than a typicaly 39 of a double.That makes a difference too.The other bike may have longer stays.That makes a difference Having been a 7 0r 8 speed has nothing to do with it. Solution is don't do it. If you insist,you could use a BB spacer,chainring spacers or maybe try a thinner chain.
