Mag bearing inner and outer race?
Just fitting a new mag bearing and wondered if the inner and outer race are solely compatible with each other or could you use the inner from a brand new bearing with the outer of a another brand new bearing (both the same make) or are they a perfectly matched pair? I've fitted the inner race to the crank but have two on the go and can't remember which inner went with which outer 

oooops their a matched pair....DOH
