Media blasting Crap! I did know about this and totally forgot. We'll see how well rustoleum holds up before I have to repaint it Also, the spring is the same size the whole length and does not fit in the cup from what I recall (I'll check when I get home) which is what confused me. If I do it open end away from the spring, it looks like it will cut into the seal there. I should have paid closer attention when pulling it apart. It was the only thing I did not take a picture of when dismantling *sigh This is why you should take pictures of EVERYTHING as you take it off the bike! *Edit: The pin holding that arm on is peened on one end and is just a snug fit on the other. I tapped it out pretty easily with a blunt punch and hammer.
