WQ Fiesta gear linkage - manual trans

[Billy99]

Hi all,
After opening the plastic transmission inspection cover to check the transmission oil, I noticed the gear shift cable linkage was broken - missing the clip and fitting that attaches to the gear selector lever. Must have been like this for sometime, still selects gears okay.
I'd like to know if anyone has experienced this problem before.
Not sure on parts availability for the linkage.
Thinking about installing a suitable size bush to take up the play, then fit a circlip.
After suggestions/ideas.

Thanks
