No biggie. It's just pins. You can buy some more. "I" would concentrate on getting that adjuster freed up. Soak it down with Sea Foam Deep Creep. It actually works better than PBlaster....and I never thought I'd say that. Soak it down HARD for a day. It'll give it up. But remember, to turn it backwards, you must hole the self adjuster lever OFF of the toothed wheel, or it will lock it from turning backwards.
