Hello to everyone, i am rebuilding my series 3 109 inch and i must change my diff flange, it is salisbury diff, i've found two kinds of flange STC4403 and STC4457(which is 607185) but these are for Defender, can you please help me finding what i need
 
series are the same flange 607185,later dust shields as fitted with stc4475 might not fit properly but you can swap your old one if thats the case

On a related note I'm having a hell of a time trying to get the nut undone, its a nyloc type and stuck fast......any ideas?
Tried air gun, big bar, hammer and chisel! Don't tell me its left hand thread.....
 
The nut on my output flange was the same, the only thing that shifted it was heat, and even then it took a 3 ft breaker bar and a plate bolted to the flange. Other way is nut splitter if there's room, you may have to write the nut off to save the shaft.
 
The thing is I just wanted to change the seal for completeness..... I don't think it leaks at the moment but if I put heat on it then it will ruin it.
Think I'll hope for the best at the moment as its all stripped down to a rolling chassis so no weight on it.
Once its back together I can put a ton of sand in the tub and hopefully that'll hold the wheels to the floor so I can get better traction on the nut....of course then I'll have to do it laying on my back underneath it:(

whack the sides each flat of the nut with a large punch and hammer it will stretch the nut easing it
 
You can make a piece of flat bar to fit the flange picking up two bolt holes wedge that against the ground and then try loosening the nut. Needs a small vee notch in middle so you can still get the socket on the nut.
