67 C10 Front turn signals

[toon]

Hi all, I'm new to this forum and I'm doing my first restoration project on a 1967 C10. Lots of good info here and some really nice trucks. After extensive research and looking at lots of pictures I have noticed that the front turn signals on my truck are mounted in the upper part of the grill. I haven't seen any other truck with the turn signals like this. The grill on my truck is even notched for the lights in the upper part of the grill. Has anyone ever heard of this?
