case 580d backhoe bucket ear/pin measurements

Hi guys I need to buy a trench bucket for my 580d issue is I'm having issues finding one in Australia. and since the backhoe is 3 hours away at my block of land I don't really want to drive 3 hours one way to measure bucket.
any one know the measurements to save me driving all the way?
Thanks
ben
