Is this under hood label legit?
 

This label is under the hood of my 1972 K10...

Yup. That's a factory label.

The pic above looks like one that comes with a replacement aftermarket carb.

Here is the original sticker on my K20

It's the same as the original on my '69. However, as stated above, I don't think it is legit for a '72. I'm not sure if it was used only in '69 or for a couple years. They were placed on top of the radiator support toward the end above the left headlight. I always thought mine may have been placed facing the wrong direction since it had to be read upside down from the front of the truck. However, it might have been oriented that way so the tech tuning the truck could read it as he was leaning over the left fender with a timing light.
