[FirstOwner69]

Here's a picture of the inner and outer grilles put on my '69 after an idiot slammed into the front of my truck in early 1972. Looked just like the one on the Craigslist truck. Both were genuine GM parts. I removed some of the black paint on the center bar (reduced the width of the horizontal lines and the paint adjacent to the parking turn signals) to make the outer grille look more like the original.

Based on the paperwork posted with the ad, that is definitely a '69.
