need help finding info on kubota BX2750C and F520A snowblower attachments

[ARMORskids]

Hi,
I'm helping someone find the bolt spacing pattern for the shoes that mount on these two snowblower attachments. If you've got either of these, could you take a measurement or two, or post some pictures with a tape measure across the mounting bolts of either of these snowblower attachments? I'm trying to help them identify what shoes they need, but it's hard because the tractors are at another location.

Thanks Everyone!
