Yeah, I'd say those look pretty worn. I would just go ahead and replace them all. Remember, they aren't broken, just worn. Prioritize and fix only what needs to be done and then replace the mounts whenever you can. I do believe the duratec and zetec mounts are similar to a certain extent, but those should be replaced sooner than later. I'll get you some pics of mine when I can. Good luck and I hope this helps.
