Best tobuy your recovery points. A Hayman Reece towbar receiver style fitted solidly to chasis can be used as rear point. You can do this by either placing the eye of the snatch strap in the receiver hole and slide the tow pin through. Or buy a receiver style recovery point.
You can also purchase recovery points to bolt onto your chasis. The factory recovery has mixed beliefs as to whether or not to use them. But the QNPCI belong to, do teach you to use it.
As with all recovery points they need to be inspected for signs of fatigue after being used, including the bolts and chasis. Talking of bolts, you need to research which type High Tensile Bolts will be needed. There willbe many suggestions, but each rating and type of metal gives a different actual breaking point. Get it wrong and you could cause a death.
I did put up a full bolt listing long time ago I"ll try to find it and refresh it inthreads.
