Makes no difference.
Sometimes back in the old days, you could find RW stamped ones on the E body cars.
No difference than B body ones if sway bar mount tabs aren't on them.
They weren't going to shut down the assembly lines if BJ stamped ones were used up in the LCA assembly line bins.
I'm familiar with 62-72 B body cars, and they are all stamped with the RW letters.
