You are in luck. Look at the screw slot in the end of the link. If you pull the carter key, you may be able to adjust the link end.

Thanks Richard.  The bus mechanic who looked at it said we could try that if I'm unable to find replacements but if we adjust them and there is a spring or part inside the end that is broken (or worn) it could cause the steering to bind making it worse.  He said that if that happened we could adjust them back where they were but I was concerned that it could continue to bind.  I guess it's worth a try.
