I need a tow ball

It will be quicker to go to supercheap and get 1 tell them you want a tow ball simple also you may need a trailer wiring harness if you haven't already got one

 

You'll also need a flat tow bar tongue

 

Would recommend going to ISP or somewhere else apart from Super Crap Auto.

 

something tells me that isnt a tow bar. it doesnt look substantial enough. im probably wrong but if i was you i would take to a tow bar shop or mechanic and ask for their opinion. and go to two or three differnt places.

 

Thats because the 'tongue' (the part that protrudes and has the ball attached) has been removed/unbolted.
Cheers

 

Whatever you do don't try and attach the towing ball to that protusion that you have shown in the photograph. You will see that there is a bolt hole (indicated in photograph) to which you will need to attach the 'tongue' with a substantial bolt. You might be able to pick one up ata wreckers. Make sure you also get a suitable bolt to secure the tongue. Good luck.

 

Are you sure you don't have the rest of it alteady? Check the spare wheel well under the carpet in the boot.

 

Go to Holden, it looks like a genuine tow bar and you need the tongue and the tow ball.
