If you get stuck looking for a frount bar that you can borrow i have one sitting around, not to sell but to get you through if you need it. The only catch is that I am in canberra 3 hours south of syd.
As far as using a tirfor, for get it I have had to pull countless trucks and caravans out of really dumb arse places with a tirfor and it's soooooo much easier sitting back with a little hand control pushing the switch back, then getting to watch the winch do the work.
