Broken Rear Compression Clicker

[mojonito]

i was riding yesterday and couldn't keep my bike tracking straight in the whoops. today i figured i would set up the rear suspension to spec and then try adjusting it. when i went to turn the compression clicker it snapped, didn't take any force to break it- i was kinda surprised it happened. i am not sure if one of my "friends" was playing a joke on me and turned it in all of the way. anyhow, all the oil started seeping out of the hole and now i have to rebuild the rear shock. besides replacing the compression adjuster, what other seals, etc. do i need to replace. there were no leaks or problems before this incident. all input is appreciated as i have not rebuilt a rear shock before.
