The best place to install the recovery points would be on the frame. There should be a 3 bolt pattern on the driver's side, so you can pick up some steel plate of appropriate thickness then drill it out to match the pattern and mount it as a recovery point.
Or, you can save yourself the hassle and do what I did which was to get rid of the tube bar and buy one with recovery points. I called and spoke with Wooders and got one shipped up to Brisbane at a very reasonable price.
If you put a reasonable price on the tube bar, it will go quick on gumtree.
