Experience w/ Graham Phantom and E.A.T. Forte S

I am working on a turntable project and strongly considering purchasing a European Audio Team Forte S to pair with my 12" Graham Phantom III. I'm wondering if anyone has experience with this combination. In particular, I am trying to find out which armboard I would need. My Graham has the custom Graham mounting plate (as opposed to the SME version).  I've contacted several dealers and the distributor, but no one has gotten back to me. Any information would be appreciated. Thanks.
