• Perhaps the mkI only need one pair of conversion plates?

    They do, but I think they are only 1mm thick. I've got to take it apart sometime, so I'll have a measure.

    There's a certain amount of wiggle room in the stack height, the screws don't bottom out if they are the 'right' length, I suspect that 5mm increments on the screw length would allow you to have proper thread engagement but no bottoming out for the full continuum of riser stacks.
