thanks mate, its just standard 14bolt 5lug diff, thinkin of ditching it and putting in 9 inch, just that i think the gear ratio is 3'75 and by the time i put 20/22inch wheels on it,it will bring the ratio to low for motor.In australia not alot of gear choices for this diff so 9 inch will work better.
