Bearing ID needed

[Grant Bowker]

I have just measured the Aetna 1570 bearings as having OD 2.212", ID .0875". The set of Aetnas we used in Bob Carriere's front axle were a snug fit both into the housing and to the axle pivot pins. In appearance the Ahlberg 928 bearings are very similar to the New Departure 928 bearings.
