long.  McMaster 6381K446.  Drilling the hole on mine at .55 would not
leave much material.  0.437 would work though.  Drilling out an E-Z Loc
may work too if you could find one long enough."

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?
