bearing spun in housing

Ok ive read how the green bearings work and from what i understand if you run these you no longer need to worry about the housing being worn? They just bolt in behind the backing plate? Its basically like a modern day fwd bearing or hub assembly. This may be my best bet if the outer race is not snug in the housing right? This car is going to be primarily a drag car and im picking up a narrowed dana 60 tomorrow for next year when the 440 gets done. Dont really want to spend too much because its coming out anyway i just want to drive it for the summer. And my apologies to the people running the yukons i only read part of these threads and it was installation errors. Please let me know if im correct on these green bearings or not. Thanks again FABO!
