Good to hear on no machining. I'll have to try a set out sometime.
And I believe it about the old 12g's. 20 years ago those olds 350 diesel were still around, because I remember my uncle having one in a car and driving it. I still make fun of him for his obsession with that car. But I haven't seen one of those in a decade, even in junkyards.
The plugs I bought weren't rebranded anything, 12g's in acdelco boxes straight from the gm dealer. He said they were one of the few sets on the shelf at the warehouse. I remember back then reading online about them having a shelf life. It was something about moisture getting in them and that's what caused them to explode.
The 12g in your post doesnt look anything like the 12g plugs that I have which is why I thought they could have been reboxed. I have seen many 9g and 11g plugs (original for 6.2 and 6.5) that were just rebranded alites. some if you looked close enough you could make out the alite part number under the slashes that were stamped into the body.
