Reynolds G650 gravel wheelset setup help!

[C40_guy]

Just bought a Reynolds G650 gravel wheelset (via Excel Sports) and am having some challenges.

I'm planning on using this wheelset on my LiteSpeed Watia with Ekar 13.

First, I ordered a Reynolds/Ringle NW3 freehub but the body is wider than the installed freehub and won't install.

Does anyone know the correct (Campy style) NW3 freehub for this wheelset?

Also, I'd like to install Campy Ekar rotors on the wheels, but the Campy lockrings go on the outside of the hub and the hub seems to be threaded on the inside for lockrings. Thoughts on the correct lockring for this application?

(edit: looks there are a number of third party lockrings that have the external threading for the hub.)

Many thanks!
