Wilkinson VSVG sting spacing

[Keifer]

I'm interested in this tremolo but confused about the spacing. One web site has it at 2 1/8 and another at 2 7/32....
Does anyone know which it is?

10.8mm or narrow mex strat .

10.8mm or 2-1/8". Definitely NOT wide vintage spacing. As a matter of fact, all current Gotoh production non-locking trems have the same 10.8mm spacing.
