X3 Ballscrew 1605 Recommended Fitting

Thinking of purchasing and fitting 1605 ballscrews (X,Y & Z axis) to my X3 as part of CNC conversion. Would like advice regarding bearing supports and ballnut mounting. Is it best to use BK/BF12 bearing supports, or modify the X3 supports? Worried about how to get good alignment. If anyone has photos of their 1605 install on an X3 please share...

Thanks,
Mark
