Hey guys, I am trying to order a 223 mag box for my center feed stevens. Is this the right one? I cant find anything that is says that it is center feed or staggered feed. I want to make sure before i order so i can make my rifle a repeater again.

And is this the right replacement spring for a week ejector?
