long. McMaster 6381K446. Drilling the hole on mine at .55 would not

This might work, although the bushing's wall thickness would be only 1/16"; you would need to slot the bushing lengthwise and use a clamp as per original, dispensing with the set screws. And, down there in VK land, don't you guys use "grub screws" instead?
