What Are These 3 Diff Numbers For?

[MattyZ]

Hey all

i was looking on the diff from my ta22 and found these 2 numbers and was wondering what they meant

 

one on the center around the bolt pattern has a stamped E then a bulging 21 picture below

 

and on the center it has on a tag X 21

 

 

if anyone can shed some light on these cheers

On the Body plate...

 

E is a 7.1"

X is a 142mm

21 is 6.667 ratio.

 

I don't know if this will be anything to go by.

I should of mentioned that E & X are the pinion size.
