40+ years I've owned and worked on GM cars & trucks. I'm sure all of us has touched just about every part on our trucks. Today I noticed something I've never seen before. While going through boxes of stuff, I found an "8-350" fender emblem with broken studs. Looked at the back side and saw a tiny bow tie near the 400 part #. I've seen dozens of these, yet never noticed the bow tie.
Thinking I might need new glasses.
