Steering Column, coded as a component?

[genminmar]

I was looking at the gas tank post and thought about other components, it is obvious when it came to parts made by other vendors that they got coded or when they came from other GM plants and had to get shipped to the assembly plant. How about an item component like the steering column. Are there date codes on them and if so where can they be found?

 They are date coded because I saw the date when I had the column out. Somewhere along the outside of the column, but I don't remember where. Also my column has an orange tag with the letters CN, I think that's the broadcast code. It's located down by the firewall. Sorry I couldn't be more helpful with the location of the date code but I'm sure someone else will have that information. RonM
