Answer: Metal tag on spindle

[Keith Seymore]

I have to apologize in advance to whoever sent me this photo (I deleted your PM before posting this):



In any event my earlier assumption was correct: the small metal tag is the part number information for the knuckle assembly, as built up at the supplier. The knuckle, including brake components, dust shield and spindle would be assembled into a front crossmember assembly, which would include the control arms and front springs. This level of assembly is what would be received at the final assembly plant and selected based on the part number code on the individual vehicle's build sheet. After being selected in the receiving/picking area (in a remote part of the assembly plant) the brake lines and shocks would be added and conveyed to the main assembly line in sequence for the remainder of the vehicle build.
