Citroen C4 VTS 180 Shifter housing

[JonoVTS180]

Hi everyone, I am in need of a new shifter housing as the one on my VTS is extremely sloppy and has inches of play in the shifter. When the car is in 5th it pushes itself so far over it looks like its in 3rd. I would like to know what I can do to fix this although I believe I need a whole new shifter assembly and cables. A short shifter would also likely help with this? and where can I order these parts being from Australia. tia
