Don't ask me why but only the rears go bad. They are about $12 at the dealer. Go ahead and do the other side.

The boys at Fastlane carry the part (shameless plug for our sponsors).

They are a bit tricky to install. Pull the track, grind the peened head off, pop apart the new jaw, insert the pivot, re-peen then re-assemble the jaw. A vise makes it sooo much easier. Use a small socket as an anvil on the pivot. You'll see what I mean. I use a chisel to "splay" the rivet.
