building dana 60 and confused.....

I am building a dana, and it was narrowed some so when I got my moser axles, they came with green berrings already installed (by the shop that narrowed the housing) so I drop the axles into the houshing and get looking at the bearrings and the retaining plate, and I'm surprised that the little tiny wrap ring is all that holds the axle shaft in the housing. I am concerned that it's not enough. (keep in mind all my axle building experiance up to this point has been on big stuff like 2.5 ton rockwells and larger so this is new to me being such a light duty axle) will that litttle wrap ring really hold up to the side loading that it will see? I would think it would just shear off and pose no resistance to movement. Need everyones thoughts here thanks.
