That's where it goes but I can't see if the guide is in the notch (the recessed area for locking into the mounting piece) I kinda snaps in and then turns to lock which helps hold the cable guide in place. On a side note that piece is one of the easiest to loose on the whole ski. LOL
The e-clips rust to nothing. Once you get guides in place correctly they stay in position without the clip. If it worries you put a little silicone on it. I never do. They are a bitch to get out sometimes.
