13" large dial crosslide bushing.

[Halligan142]

I'm currently in the process of convert my small dial 13 to large dial. I have the actual graduated dial, but I need to know the dimensions of the bushing. I realize this will likely require me to modify the actual screw, but that isn't a problem. Did the same thing on my 9" when I converted that. If anyone can spare some time could you measure yours? I know I could generally make it anything I want because.im starting from scratch, but this would be a lot easier and save headaches. See the attached picture. The smaller diameter in the middle represents the hex section of the bushing. Everything to the right.of that is inside the crosslide. Thanks
