Hipshot A & B mounting screws spacing?

[hemhaw]

Does anyone know if the the mounting screw spacing on the Hipshot A & B 4-string bridges are the same?

I have an A style I would like to replace with the simpler B style bridges?

I tried emailing hipshot a few times with no response.
Many months ago I called hipshot asking about tuner but did ask this question but the person I spoke with didn't know the answer.

The mounting hole dimensions are different from the A style to the B style.

A style mounting holes are 3/4" center to center for the 3/4" string spacing.

B style mounting holes appear to be 11/16" center to center for the 3/4" spacing.

See the Hipshot website choose A style bridge and click view product dimensions for more details.
