1. An adjustable rock knocker apparatus comprising:
a bracket configured for attachment to a truck body, the bracket having a first support and a second support;
a pin mounted to and extending between the first and second supports, the pin configured to accept a first end of a rock ejector and mount the first end of the rock ejector at an adjustable lateral position between the first and second supports, the lateral position being at least partially dependent on the lateral location of tires mounted to a truck chassis on which the truck body is mounted for transport of the truck body; and
a rock ejector pivotably mounted at a first end to the pin at a selected lateral position on the pin, the rock ejector being retained at the selected lateral position on the pin by at least one bar retainer fixed to the pin and the pin having a plurality of holes formed along the length of the pin, the holes passing at least partially through the pin, for receiving a fastener to fix the at least one bar retainer to the pin.
