Please disregard the bad swipe with a grinder; I misjudged the spyder geometry when cutting the can. I cut all three others perfectly by working upwards against the can bead.
The question I am asking is just how bad a CV Joint can wear before it fails. The indentation from the ball actually looks worse than it really is. When you run your finger down the sleeve, you can feel an indentation but its is not as massive as you think it is. Could it be that this spyder is actually reusable?
