Gear selector rod help

[Emma1985]

Hey can anyone advise what I’d potentially need to change here...
I’ve had an engine replacement and since I can hear the gear selector rod knocking when driving on uneven road. I’ve had a look and it’s very slack. It’s not effecting the gears in any way.
Any help be appreciated thanks

Spring 23 often breaks, easy to replace from underneath.
