There are ALOT of varios nuts, bolts and other misc. fasteners. Here are ALL of the Z34 NISMO aero parts on the front bumper that are different and not included on the non-NISMO 370Z.

However I have learned from past experience, you will almost always need some odd, unforseen bolt or bracket that will hold up the install.

ehh...and you can leave the tag bracket and hardware off. When I was pulling part numbers it popped up as different.
