Interesting, my RR had the first k-frame pictured, never knew what month it was made, who cared about that back then. Guess they made the change over to new k late in the model year but still had a lot of sway bars to use up. What was the first and last build dates for the A-12 cars? Did they use the same frame on all of them?
I never paid attention to the Pilot bee as to the style of K on it. My 69 Bee with an SPD of 2/10 has the 68 style bottom , so the change over was after that.
As far as the comment of using up swaybars ???? The swaybar change happened for the 1970 model year , 69 model year cars would not have gotten them. The K was obviously changed before the model year started in preparation for the upcoming change.
