Part number-wise, according to my GM parts book:
Group 6.168 ARM ASSY-STRUT, Steering Knuckle Upper and Lower Control Arm
Assy.
64-72 3974217 L.H. upper
3887062 R.H. upper
64-70
71-72 wagon
71-72 (400 w/4bc,454) 3990509 L.H. lower
3990510 R.H. lower
70-71 (exc. 396,400 w/4bc,454) 3967769 L.H. lower
3967770 R.H. lower
72 (exc. 396,400 w/4bc,454) 6263617 L.H. lower
6263618 R.H. lower
Apparently, for some reason the 70-71 and 72 lower arms are different for a
small block car. (?)
