Rear sway bar was part of the F41 suspension option on the 70 Nova. The sway bar didn't show up until late winter early spring of 70. Designs were done in late fall 69 for the part but to my knowledge it didn't come out until spring. I believe all the Deuces have it. I have discussed this with Greg Roberts on several occasion and this is the info we have. Other Nova experts may have exact dates or documented cars for reference.
