help needed with 904

The one you picture looks about right, but I always replace those.They have a tendency to wear out along one or two of the creases by rubbing on the inner race. They look good, But if you go to stretch them out a bit, they may not survive. When you go to install the new ones, there are 4 ways to put them in, and only the right way will keep the spring creases off the inner race.
