Actually, I was confused by this recently. I bought a stack of spare buggy arms and some more 4wd buggy arms, and when they came in I thought they screwed up and sent me just B44 rear arms. However, in my brand new B4.1 FT kit (and marked B4 on the tags on the spare rear arms), all the rear arms had two balls. Interestingly, they were not inserted in the bag the same way. One had the bend in the arm closer to the tag and the other had it down, and they were consistently that way. I assume this indicates which is which, but there's nothing about the arms themselves that provides any indication of how they differ. I'd just stock one type if I knew the B44 arms were equal or better than the B4 rear arms. Just one less separate line item to stock...
