1970 Nova rear sway bar ?

[JRSully]

FWIW, If your hunting this complete set up, always check the build date, As Marlin stated, they only appeared in the 2nd half of the 70 model year. Anything built prior to Jan 70 would probably not have the set up factory installed. Also, if you find a potential car that has it/had it but the bar and links are gone, check for the floor welded upper mounting brackets anyway. If the car was cut up (raced.?) it was almost certain the bar was in the way and chucked, but rarely would the welded brackets be removed. Grab those anyway
