G'day everybody, happy Easter. I'm after some help identifying a Chev truck. Its an Australian Holden Plated RH drive. By the serial number on the id plate it comes up as an 1130 or 1140. What does that mean? On the side of the bonnet there is a badge that says 1100. It has a flat tray on the back with dual rear wheels which are 20inch in diameter. I read people talking about 1/2 and 3/4 ton pickups and trucks so what size would this one be. Are the bodies all the same no matter what the capacity? Can I put a tub onto the back and turn it into a ute? Thanks in advance. Ron.
