I bought a sweet grill from a member here on the site. Using it I designed some custom badges that I haven't cut yet but will cut later and have my sign painter brother fill in with color.
grill-
The GMC logo continues the center bar through it. and is a bit larger than factory-
Engine Badge-
kinda mocked up-
They should be neat. The GMC and engine badge have the upwards angle in them that the factory ones have. I'm waiting to get the truck together though to ensure the factory angle is good for seeing them based on the height. The truck will have about a 4" lift kit, on 35's/20's.
