Those charts are a perfect example showing how the GM service organization collapsed multiple production part numbers into more common use service part numbers over time. The first chart is from 1969 and carries a more diverse listing of part numbers, but still not all of the production numbers used in the factories. The second chart is from 1971 and the consolidation of multiple part numbers into one part number has already started. If you followed the chart out later in time, you would probably find only 2 or 3 springs that would service all 67 to 69 Camaros.
