Palewin, thank you for your reply. The SPU cartridge is integrated with the head shell, so I can't move the cartridge itself back and forth. There is only one solution in my opinion and that is to adjust the spindle to pivot distance a bit, so the overhang would be correct. I suppose it is more important to get the overhang correct even if the measured spindle to pivot distance deviates a bit (a few mm's) from the specified value.
