You will not be able to cut additional threads on a good skewer because the axle is heat treated cro-mo and the threads are rolled before heat treating - like spokes. The threads on the one I have is M5x0.8.
On a budget; go with the 130mm, and if it will not screw on far enough, put a serrated washer in between the frame and the end of the skewer.
