Australian M816 wrecker build.

[Ron King]

The Aussie ones were the same in concept with the same pins, but the main body of the holdfast was a steel casting and thinner in the body of it.
The pins were angled the same.
The Aussie holdfast did not use a pin arrangement to join them together, but had a hole in the end of the body which took a large D shackle which was normally left in place.
I remember it well..........having to knock in those pins into the ground with a sledge hammer in rocky ground,40c degree heat .............and having the drama of trying to get those pins out again.
Then having to lift it all into the back of the wreaker which is shoulder height on me.
