* Change 6 Part Black {6628 Technic, Pin with Friction Ridges Lengthwise and Tow Ball (Undetermined Hole Type) to 6628a Technic, Pin with Friction Ridges Lengthwise and Tow Ball with Round Pin Hole}
Comments from Submitter:
I can confirm that this set contains this part with round pin hole. I keep my old Technic collection separately. I have 4 parts with squared pin hole and 6 with new, thinner walls in those sets: 8008, 8010, 8420.
Also here are visible this parts with round pin hole (in the wheel):
