and perhaps a few more things...but I forgot
@ Stratton: the lip on the NX fitted reasonably well, but there was quite a gap between the headlights and where the bumper starts, so I had to fill up a half an inch wide gap there.
Oh, and it cannot handle the effects of a NX pressing it against a guardrail at 80 mph..... (I was pushed off the road, got in a spin and crashed against the railing. The guy who pushed me off the road pulled a nice and friendly hit-and-run on me

). The NX was totalled, unfortunately
