How to change thread indexing with G92

Hi,

I have a part that has an internal thread at one and and an external thread at the other, these parts screw into each other and have a hole on one side. currently when the parts are all screwd into each other the holes all line up down one side. without changing the tool offset or trimming the part a little to allow it to screw on another half rotation, how can I have one of the threads start 180degress from where it currently does.

Done on a cnc lathe, holes on side are drilled in a manual mill

My threading command for the internal thread is

G92 x28 z-9 I24 J3 K1
x28.2
x28.4 and so on

Thanks
Darren
