Tow-bar availability - '70 VW Beetle

Hi, wanting to know if there's a tow bar set-up available for a 1970's VW Bug (standard). Looking at towing a small camper trailer or tear drop van. Any ideas as to where I may find something that'd do teh job that's legal in Australia.

If its a swing axle I have a factory tow bar that attaches to your frame horns. Where are you located?

Located in Caboolture.....Ok, so here's the question that tells you that I'm a reall 'newbee'.....How do I tell whether it's a swing axle or not ?

also have one for 70's
extra support behind bumper
has plug ready for wire also
can drop by in 2 weeks
