Yes, they totally butchered the second iteration/AB suffix versions with the offset/stamped water neck. One of the stupidest things they ever did.

I had the opportunity to ask an engineer on staff during that time why they made that decision. He agreed it was an incredibly dumb idea.
He related why, and the reason why may have been ever stupider than the decision itself, if that's possible.
Maybe we can get into that later, it's all ancient history.
