Column Base dimensions

[Winnfield]

I am evaluating the column of an X3 for use on a machine I am building, and would like to know (if someone doesn't mind measuring for me) the approximate bolt pattern of the column where it bolts to the base, and the L and W of the flange. Thanks!

bolt pattern approx 2.75" x 6.5"
flange footprint approx 3.75" x 7.75"

Thanks! I really appreciate it.
