“I’m blue da ba dee da ba di…” 🔵

Custom blue and black GMC Sierra emblems done the 404 Parts way. OEM GM parts, hand prepped and refinished by our small business for the truck guys that want something cleaner than stock and way better than overlays.

These things hit different in the sunlight!

🇺🇸 Today we remember. Today we are thankful. Thank you to all that have sacrificed all and their loved ones that carry that as well.

Cody and I decided to do a special USA set of emblems. One for the 404 Parts CT5-V and the other to send to to put on the .factoryusa Blackwing. 🤞😎
