Here are pix of my latest mod - Courtesy of Crazy Paul!
This Holden HSV - VT-VZ Badge, which I also used in all of my wheel centers, is slightly larger than the existing Pontiac "V". By bending the badge slightly to give it a bowed curve, and using a couple pieces of double stick foam tape, it fits snugly over the Pontiac badge. It also has it's own adhesive, which keeps in positioned correctly.
