RD: That's easy....the Classic ain't a real M70...it needs fixing.
But I see your point and it's a bit different. All we are doing in replacing the MIM extractor on a Classic is sliding the thing off and popping on the same design made from a different(correct)spring steel model. We are not re machining anything and cutting into those 3 rings of steel,which is a real alteration of the Rem 700 design.I figure I will follow along with the Remington design engineers
All I am saying is the Rem extractor has always worked fine for me and if I want something that I think is more robust I'd just buy a different action.
