you have to undo the tailshaft bolts ( 4 12mm nuts) the 8 U bolts ( 8x 14mm nuts) i drop the spring hangers down just to make it easy ( 8x 14mm nuts) and the brake line ( 1 10mm screw thingo and this bit of metal that holds the brake line in which you just use some visegrips to pull out) and the hand brake cables (undo 4x10 mm bolts which tension the line and the flick these rubber things that hold the line on the car or when you don't need the handbrake cables such as speedway just hacksaw or bolt cutters through the hand brake cables) sounds like alot but about 15-20 mins work max i have changed a fair few diffs trying to get the right ratio for speedway
