Is this for the light blue air line or the black air line?

The 170114 is the newest version of the bulkhead fitting kit for the ARB Air Locker. This bulkhead kit is for the larger 6mm black plastic external airline and the 3.5mm copper internal air line. I adapted to my existing steel mesh covered line so you can do a lot with it.

What is the size & thread pitch to drill in the diff ?

The tap is 1/4 inch NPT, which requires a 7/16 inch drill bit. Start small and work your way up.
