Based on previous Ford Performance history and what ghost said, at this time Ford doesn’t have any incentive to offer up the fix to all cars affected. Some cars with the 3-bolts will have no problems at all, so Ford would “waste” money by changing them out. So, if you have a failure Ford will repair it and install the correct part. It’s all about Ford not seeing any liability problems, only a few cars that joyriders break. Even then, Ford will attempt to deny any warranty if they can.
All this is why I just bought the correct part MB5Z-5035-E for mine and will replace it myself, so I can run the E50 tune!
