This was asked by a Member of TKE on another thread, and my advice was "While they may be a Legacy", If they do not fit they dont fit. It is up to the individual Chapter to decide Yea or Nay.
As was said, if they are a real tool or a problem of not fitting into the formate then dont waste your time and maybe lose someone who would really be a hand in glove fit.
The idea is to keep building and lasting.
