TRNW-2: 10R80 CDF Drum Differences

[Healy Powertrain]

I went thru the same thing last time I ordered a CDF drum. Even looked at the pictures to see if there was a difference. Friction count is the same . Couldnt find a difference.

If you go by the Ford Number Coding:
J=2018

M=2021
Since the rest of the part number is the same my best guess is M supercedes J
