I need to look at it again.

Is the trans an M20, or M21?
The transmission was a "free" selection (M20 wide ratio, M21 close ratio, or TH400 auto). But if the M21 was picked, the 3.73 ("performance axle") and heavy duty radiator were mandatory inclusions.
My guess is original buyer or dealer that ordered it simply checked the M21 box, and the 3.73 and HD Rad were automatically added to the invoice.
Yes, the axle tube should be stamped COZ.
