Do Graham 2.0 and Vector 3 have same cutout?

I have Graham 2.0 mounted on my Basis 2001. Thinking about upgrading to Vector tonearm. Does anyone know if they use the same arm cutout? Trying to figure if I would need to send my plinth back to Basis. Thanks
Unfortunately no.
I just talked with A.J. at Basis audio about the same subject. They are not the same bore. You would need to get the plinth plugged and re-drilled for the Vector.
Thanks for the quick responses.
