I am having trouble identifying several Dana axles I have. Having completely cleaned them up, removed all grease dirt an crud down to the bare metal, I cannot find one identifying number on them, Not on the flange, the nose, nowhere. Am I the only person this happens to? My question is can I compare the covers and identify anything? With 8.5, 9.75 and 10.54 ring gears are the covers the same size or do they get bigger with the larger ring gears? I can remove the covers and measure the ring gears but hoping for an easy answer here. :help:
