You can see the two locks right here. The top one has its original rod bracket in place while the FC one fits perfectly. You can also see that the side \"wings" are too thick to slow into the door handle.  When grinding these "wings" down, make sure the lock is oriented straight up and down.  Getting it crooked slightly may result in you not being able to fully lock or fully unlock your door.  But I did find that there's a little margin for error here.  Plus, I had an extra lock if I needed it.
