Hello, on mine there were no shims as you mentioned, just the large diameter bearing that rides between axle and hub , a seal that goes on inner side against the bearing and a retaining clip that fits in a groove in the hub. Hopefully get more posts .Note the large bearing has been a source of earlier posts with the repro ones being a item of criticism. Also on mine the brakes have been converted to hydraulic so rear hubs been changed from original.
