That's the gist of what I was getting at in the following thread. I was surprised what I found when searching the part number vs what was the spec for my F87 rear end.
I felt better that everyone else was getting a similar part number, but I agree, there's still some questions about what's going in. BUT, if it's what they're calling for, I'm satisfied from a warranty perspective.
