We use these 1968-74 Nova lower control arms on our GM midsized metric-based modified chassis. This widens the front track width which vastly improves handling.
These are stock Nova GM metric lower control arms. Each has been sand blasted clean and has had the ball joint removed. The used rubber bushings should be removed and replaced with our steel bushings.
91634036 is the rear lower bushing
91634030 is the front lower bushing
Order control arm as needed for metric chassis, i.e. 91034300-R is for the passenger side of the chassis. Right-hand arm shown in photo.
Center of ball joint to the center of the bushings is 16". Outside to outside of the bushings is 13-1/4". Inside of bushing to the inside of bushing is 8-7/8".
