Cletis: The info I placed regarding the serial number for which the part number of the pinion bearings change was just for illustrating that there were more than one part number for the same bearing. I had no idea what that meant until you brought it up. It is good to know. Regarding Oakland, the change came for serial 100-24C-Z5201, no info on St Louis on my books.
Hope this helps
