Case != carrier. OK if you are talking about this internal carrier, I was not so we were talking about different things here. You can see I admitted I did not know about the internal carrier.

I'm still surprised steel is not used for it. I wonder if the weight savings is so important or whether the thermal expansion properties are the more important consideration. Cost of magnesium alloy surely must be greater.
