Heres a pic of the 1st 67-68 Chevy grille during its test fit installation into a 68 Suburban. We also installed it in a 67 Chevy truck and a front clip assembled from all reproduction parts from Tri-Plus. I'm happy to say it was as easy as installing OEM. The grille mounting points all ligned up in all 3 installations without having to elongate or open any holes, all trim pieces, hood latching mechanism, lower splash shield, braces, etc....all lined up great.
I'm also happy to say all double radiused curves are smooth and wrinkle free with body lines being crisp and clean, inside open radiuses had no tears or distortions from stamping.
