I have seen Broadcast sheets for a few 1969 SS Novas, and none of them list an SS option. Looking at the assembly manual, the instructions for L34 and L78 point to the assembly instructions for L48, which call for the SS trim to be added. Note that I am not trying to say anything specific about the Yenko in question, since I have never seen it in person, and there is always the possibility that it was not built per the usual rules. But per the normal process used at the time, any L78 car would get the SS trim, and no Z26 code would have appeared on the broadcast sheet. But I have seen a 1970 Nova broadcast sheet with a Z26 code, so go figure. The broadcast sheets that I have seen are all from the Willow Run plant. These sheets were small, and did not have many spaces to list option codes, so I will conjecture that they were not listing some redundant codes to leave more open spaces on the form.
