Hi everyone. My name is Hermann. I have a problem trying to replace the rear differential of my 2009 Land Rover Defender 90 2.5 TD5 manual 6 speeds. VIN SALLDVB589A781460. I donīt how the number of pins, bolts or splines , but I can see the number HRC1124 in it. I know this is not the part number but I shall be very grateful if anybody knows what type of differential I have to buy. Thanks in advance
