I think if I was Dorian I would have worn out 2 sets of kneecaps kicking my own ass! Good for you! Did you replace your 2004r with a Muncie? Did I read that right?
Id be surprised if the component that ran through that center where the clip and seal were damaged did not also show at least minor damage, that bent seal and retainer obviously were deformed with a good deal of forces at some point.. or was that the result of a tool used to remove that component?
