Question about Babicz trem string spacing:

[Mapleg4]

Just wondering: Does the Narrow, Original Series Babicz FCH ST-Style Tremolo work with the Vintage 6 Hole Tremolo routing or is it too narrow?

 

[Fat Pete]

I would expect that a modern-style bridge like that would be offered with wide mounting screw/narrow string spacing option, but it appears not.

 

[TBurst Std]

Not sure.  String spacing has nothing to do with mounting spacing.  There are 2 widths for each and every permutation has been made over the years.  Terms of vintage and modern should be considered meaningless. 
Get dimensions.
