Need to find out correct bb size for the following frames.

Rocky mountain stratos 1991, needs a frame saver type as threads are gone.
Will be using a dx crank from same year or Shimano STX RC crank

Klein pulse 1997, Will be using a Shimano STX RC crank.


Any help with sizes or parts would be great.

Thanks
