I do not have one --- stock manual steering here with my 69 .
Look at this Post : using stock Nova sub-frame ... with some pictures
Then look here -- they make a R & P kit for 3rd gens :
nice kit ... if I can win " Power Ball "
you asked ..... :yes:
I did the Steeriods rack & pinion kit on my 72 BBC nova. It went in pretty quick. I like the way it feels compared to the stock steering setup. About the only thing I didn't like was the price and the turning radius isn't as good as I like. Other then that I'm pleased with the overall kit.
