Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
I pulled a diff out of a vx the other day and the last axle bolt stripped(the Allen key bit)so it was weld a 17mm socket on it and got it,but I second your motion they where all tight with a bit extra!!I don't see how those bolts could get flogged unless someone has stuffed them trying to remove them. Those bastards are tight so I don't see them coming loose, they also use a steel locknut from the factory to prevent them working loose.
