Update for This Thread-
The NRG short hub for the s13/14, 200sx,etc does work with modification. I received my NRG short hub 2 days ago and after pulling it out of the box had my doubts as to whether or not it could fit. After some test fitting I discovered that the hole is too small.So I just bored the hole from a 5/16 to a 1/2 and it fits very snuggly with the addition of a spacer. I will snap some pictures for those interested later today.
