Help decoding Differential
I was wondering what I have and I don't know much about the numbers. Is there s a guide somewhere to help. The only number I saw was facing rearward and upside down. It was 3871375. Is this the right number to look up? Can anyone tell me what rear end I have from this?
Thanks in advance

For your information 1973-74:
Code - Ratio
AA - 3.55:1
AB - 3.70:1
AC - 4.11:1
AW - 3.08:1
AX - 3.36:1
LR - 3.36:1
A simple check would be to rotate the rear wheel one revolution and count the number of turns the propeller shaft makes.

Not sure about a 1973, but the rear axle/identification codes may be stamped on the bottom of the differential and hence may not be visible.
