Which Nissan aftermarket grille is the least pain to install? I am generally a DIY person around the house, but not necessarily automobile DIY savvy, but I want the look. I bought a Carriage Works Grille (4 pieces, which had many nuts and bolts), took it to an auto body shop for install and they wouldn't touch it. I have since seen an E & G model and T-Rex (I think both look more polished) so I plan to return the CW and buy one of those. Has anyone installed either, and is it difficult?
