The way the kick lock works is just by pushing a metal pin into a metal plate that has valleys and ridges. That metal plate is screwed into the same spot as the disc brake

The original hub has markings on the top of the hub that indicate where a valley in that plate is. You can add these markings in with a white paint pen.

Lightly screw in the metal plate into the new hub for reference

Try to replicate the lines on the original hub by placing the lines on the new hub lined up with the center of each valley in the plate.
