includes part numbers.
If they replaced it with the original OEM part, I am not sure I'd worry much about it (unless you spend a lot of time northward). Even then... it took six years to crack, so it's probable that you won't own the car when it fails again (if it does).
Nothing to really be that concerned about, IMO.
