I understand that some may feel the positions of AF points may lack in certain models, but that was not the point of the discussion though.
The mirror box of APS-C cameras is as far as I know always a bit smaller that the mirror box of full frame cameras. But you might be right, and maybe the bottom of the APS-C box is exactly the same distance to the optical axis as that of the FF box in cameras.

Actually, the distance to the AF-module is the same (has to be the same). The mirror box itself may be a little smaller, at least, if you don't include the AF-module itself in the mirror box assembly.
Kind regards, Wim
