Rail (625Wh) Trek Rail 220mm rotors

[Gazzaaitken]

Any know the correct shimano part number for the rear post mount, for fitting a 220mm rotor on the rear?
I have a 220mm on the front, but looking for a bit more on the rear.
Burnt the 203 on the rear doing the last Munro descent.

Running shimano xt 4 pots

Thanks

Correct part numbers for 220mm rotors front and rear, using shimano past mounts are sm-ma-f220p/pm (rear), sm-ma-f220p/pl2 (front)
