Nope. Some early 73 got the small ball joints. I've seen one with my own good eyeball. I forget which month it was, but it was before January of 73 and was a 73 model Scamp. I know cause it was mine. I THINK it was an October build date, but I honestly cannot remember. That's been a long time ago. But some really early 73 models did come through with the small ball joint.
