can any one help me

hey guys i have a 1981 ke70 panelvan with a 12a rotary in it i have had to change the gearbox out once cos i smashed third gear Now I'm onto changing the diff but have no idea if it is the original one, I'm assuming it is. It has been locked and i have completly destroyed it i pulled it apart and have now got the centre out and on the crown gear it says 35:9 is that the gear ratio? Because i need to know what kind of centre to put back in as this one is not repairable. and also i looked on the plate on the car and under trans axle it says s312 that is the standard diff type which is S=6.38, 31=3.909 ratio. So is there any other way of finding out if the centre is tha stoko one? ill post up some picks of my car soon only jus found this site :bash: [/size]
