Perhaps Rich is on target. Taking into consideration they just neglected to delineate like you did in your post for the Camaro for 67-68. I have had my head in these books for many years and if I had to make a call on this at this point I would say because the 69 has the separate listing for the Camaro it is the correct p/n for the entire year. Especially since the 5690846 was apparently not being mixed with, or used instead of, any other part up to 5/70. Sorry if my 2 cents upsets you Jeff but what do I know anyway.
