there is a company call

Fit perfectly for my 2012 370Z. i do i little bit research before buying and then i choose them, very nice quality. the hardest part of doing it yourself is to find the size of bolt to screw into towhook, then you have to do welding(something that you can not) i giveup after many time come to homedepot
if you are nismo or amuse,stillen...make sure you choose the nismo edition
