I've seen that arguement before too. But in all my years around cars, I have seen precious few c clip buttons broken. They don't hold a load at all. They simply keep the axle in place. It's a good rear end.
I've actually been looking for one for a long time to trade for my complete 8 3/4 sure grip under my 63 Dart, but no one's ever come through. I guess my little slant car will just have overkill, and that's fine too. lol
