how do you tell the difference between a SWB mk1 and mk2 axle

i know the diff input flange is different but ive descovered this will swap, im now thinking my mk1 has a mk2 axle in it just seems to be identical to the mk2 axle i have or were they identical
what about the wheel studs/nuts were they imperial on the mk1's

My Mark 1 was made before Australia converted to metric in the 70s; didn't the U.K. convert to metric at the same time?

One of the differences I have noticed is that the brake shoes in the Mark 2 are wider, which is in good part why I want to update my Mark 1 rear axle.

OOPS!!! Disregard that; only now I noticed that you said "SWB" and my mind is still on dual rear wheel axles,.. but it might still be the same difference with them since Mark 2's have front disc brakes.
