Will C7 RS6 CCB rear brakes fit on a C8 RS6?

[JohnEnglish]

A friend is looking to retrofit CCBs onto his C8 RS6 and he can get a good deal on a set of rear CCBs for a C7. They're the same size (370mm x 30mm) so he's thinking they should fit but he'd like to confirm if possible before buying them.

Yes, I have the part numbers but just because they're different doesn't mean they won't fit. There are a few parts from my B8 RS5 that are interchangeable with parts on my B9 RS5 even though the part numbers are different.
