Well guys thanks for the research work. I have been trying to sneek in a few minutes to get back here. I got over to my shop over a week ago and got the other cups out of my second drum and the outer # was hyatt 11035=Z, and inner hyatt 11424-Z across from those #'s i found #52Y stamped on both cups. I forced myself up and down the stairs (recovering from knee surgery) at the shop and looked in some of my old parts books. In the CR bearing book it refered to 1938 to 59 4100/4400/4500 w/Lt duty axle useing inner #B44, outer #B45 and 2 seal opions 2.063 dia. 20669 or 2.094 useing 20975. The other choices went by axle sizes one being FE 900, or 585F, or 586F. I wrote all the numbers down but not sure how to figure the axle size out. Any thoughts. At this point someone at the local bearing supply house has to have cross overs, or I can check on line or if one of you have anything. gotta go it's late and I need to help the wife get to bed and so thanks again.
