Hub nut size?

I've got a 2002 R300 Superlight with a De Dion axle and Ford diff and I'm replacing the rear pads/discs tonight.

I know the torque setting on the large hub nut is 270nm but can anyone tell me what the nut size is please so I can get the correct socket to fit it.

Somebody suggested it 'might' be 42mm?

Cheers,

Si

Yup 41mm Maybe someone local has one you could borrow. They are costly. I have one here.

I'm sure I paid about a tenner for mine. And then promptly ground the heck out of it so that it will fit through the centre of my wheels. Rope a mate in to help stomp on the brakes and get a whacking great breaker bar to undo those nuts. And remember that one side is a left-hand thread.

If it helps re handedness.... 

From the Assembly Guide: Place the thrust washer over the driveshaft and secure using the 41 mm nyloc nut (LH plain insert, RH green insert) noting that the LH nyloc nut has a LH thread. 

ETA:  If you plan to buy a socket, there's a good offer here: http://www.drapertools.com/product/26669/Expert%2041mm%203-4inch%20Square%20Drive%20Hub%20Nut%20Impact%20Socket

Thank you everybody for your help, advice & input. I managed to borrow locally a 41mm socket.

Damn; 200 lbft is tight to undo !!!
