Bx25 backhoe bracket measurements

[CrashmanS]

I have a Kubota Bx-25 and also have an extra trenching bucket that someone cut the brackets off of. Does anyone know the hole to hole measurements of the mounting pin holes for the bt601 backhoe? I have access to a cnc plasma cutting table and would like to burn two new brackets and weld them to use this trenching bucket and possibly build a root ripper.
