Wheel spindle width

[Ted M]

Afternoon oil cooled OSS land. I need a favour. I need to know the width of a B12 mk1 front wheel spindle and the width of a GSXR 1100 usd forks front wheel spindle (any model as long as they’re upside down forks). It’s a complicated tale but I’ve got 2 wheel spindles off a GSXR 1100 with usd forks (allegedly) both are the same width and both aren’t wide enough to go completely through both sides.  
 

Once I know the width of said wheel spindles no doubt it will throw up more questions. But at the moment it’s doing my head in. Many thanks in advance and a beer to the first one who gets the answer
