The 1960 - 1966 Chevrolet & GMC Pickups Factory Correct Restoration Thread

[cortcomp]

Here was a number near/above/behind/left of the power booster in my truck. It is a 66 with factory power brakes. I only saw this number after getting through the OEM paint in that area, hadn't seen it before and as soon as primer went on it was gone. I think the item used was called autopen or something? It's a bunch of tiny dents that it's drawn with. Haven't been able to line up the number with anything yet, but didn't put a lot of info into it. If i recall when i decoded it, it's a fremont truck.
