I used that diagram to determine the orientation and found the mounting hole in the middle of the bumper. Just like you said. I originally thought the mounting hole was for the front license plate bracket.
Thanks, I ran into the garage and have already put it in it's rightful place.
... nice type R bars by the way, could this be a early model Type R? Hmm, i don't think so now that I think about it, the type R had only 1 toe-hook, you have two. But still, white NSXs are nice...
