I purchased and stuffed a steering column in my 2nd Gen Camaro about two years ago and now I can't remember the year of the Camaro I pulled it out of. I have found two numbers inside the column once the turn signal switch has been removed. They are 7805273 and 7804176. I called Chev and they informed me that their computers do not go back that far. Are there any spec books that I can review to find the numbers and the year this column came out of???????

Any help would be greatly appreciated.
