Hi William
I have the same NRG short hub as well as the NRG quick release similar to yours.
I did the installation yesterday but I noticed that there is about a 1/4 inch gap between the hub and the flaming river steering column housing ( not sure if it is the right name for it).
The hub is fully seated and through the steering column shaft splines.
Not sure why the reason why there is such a gap shown in the below link
