i just got a reply from a tech at clevite, these bearings are old and must have been on the shelf where i got them for a long time. D.A.B. stands for Detroit aluminum and bronze which became Michigan then Michigan 77 and now Clevite 77 and the new replacement bearing is ms877p. so if anyone else pulls these old bearings out of a motor now you know what they are.
