I have probably pulled 50+ 660 housings from junk yard cars and pick ups. I have one on ebay right now. The number on the base seems to be 1968 and early 69. After those dates they all seem to be numbered on top. Most of the cars were full size from the Janesville plant. Earl

That is an interesting observation. I have seen and inspected several early BB 69 camaros that have the 660 on the tube and the provision for the spring. My 9B 69 BB survivor camaro is configured this way as well. My thinking was that it had something to do with different suppliers they used on any given day, week or month. I have not observed the pattern you suggest.
