I have in the past seen a chart listing all the various bearing part numbers for Triple M cars (mostly ball races) but I cannot think where. Possibly an old Infoletter. Couldn't find it on a forum search. Anybody?
For those less familiar with the website, this chart and much other information can be found from the menu on the home page "Document downloads | Technical" then choose the sub system, in this case "miscellaneous". If you have any technical information you think might be useful, if you send it to me (as a .pdf) I will add it. Nick
