69 C10 6 Cylinder Engne Codes Help

[tuskiso]

Attaching copy of my glove box sticker. Don't have manual. Just acquired vehicle last week. Very few docs. Also, I don't see a transmission option, so hopefully that suggest that the 3 speed might be original. By the way, I appreciate your time and assistance. I acquired this vehicle as a donor vehicle to restore an existing 69 C10, however, after receiving it, it appears to be in much better shape than my existing C10. If it turns out to have the original power train. I will probably keep it in tact and do an owner restore back its original look (except for the converted floor shifter). Thanks again for all of you assistance. Please review the sticker and let me know how this might help me toward my end goal.
