Tonearm mounting differences Graham vs.Tri-Planar.

I would appreciate for explaining mounting differences Graham vs. Tri-Planar.
Is the high is the same for both?

In other words if I can place them on the same arm board (plinth) and only mounting holes drilling pattern would be different, the high would be the same, not requiring any high adapters, transition panels?

I have a Graham and the arm height is adjustable as it is on most arms; in most cases, not all, only one height board is offered. In all likelihood the same board will work but I have not used a Tri-Planar; is it also adjustable for height?

Yes, the Tri-Planar has adjustable high as well.
I am not sure if the same board would work since highs are different.
At worst case I would order the custom arm board.

Rokokono,

The same height mounting board will work for both arms. I've seen it done on more than one table.

The hole drilling patterns are quite different however, as are the mounting distances from the TT spindle. My suggestion would be to have a board dedicated to each arm.
