Control Arms

The upper control arm alignment cams are the same from 64-76 if I remember correctly. 3/4" hex, 3/8" shank with the eccentric on the bolt. The ball joint size was the same from 63-4 until 1972 for drum or disc. In 1973 the 10" drum and all disc cars used a larger ball joint while the few remaining 9" drum cars got the same early small ball joint.
Lower arms used the same size nut on the lower pivit shaft, used the same T-bar retaining clip, same lower bolts for the shocks, same nut for the strut rod...
