22G1128 pretty sure didn't come out in a Mini K/early Clubman with a 3.44 diff ;)

Yeah, some early cars had a 3.76 diff, but most are 3.44.

I beg to differ, my Mini K parts book lists 3.765 and 3.647 ratios, NOT 3.44.
The only 22G1128 boxes I've found to have a 3.44 in stock were Mk2 S and GT.
My car has a box I took out of a GT, its diff ratio was 3.44 until I changed it.

The UK 1275GT (with way less power than ours) had a 3.647, I'm not aware the Oz GT ever did.

re 22G1128 boxes-
IMO- "If the box has rubber U/Js and is remote shift it is either off a Mini K or an early 1098 Clubby.
If it has rubber U/Js and a puddin'stirrer shift, it is out of a van, or a Moke.
If it has Hardy Spicer steel U/Js and the cluster gear has 22G1040 stamped on it, it's a Cooper S or Clubby GT".

However, 40 years on as it is, things get swapped about, anything is possible. :lol:

If it has Hardy Spicer steel U/Js and the cluster gear has 22G927 stamped on it, it's a Moke".
But as The Doc says This may have been changed over the Years

The 4.13 and 4.26 were used here in bigwheel Mokes and some Morris 1100s.
I have a good 4.26 CW/P for sale if you are interested...

[edit] You can fit this ratio to any box.
