1090 Adv R Rear Break Master Cylinder

[Fordster]

Good afternoon All, I need some help please. I need a KTM 1090 adv r Rear Brake Master Cylinder Rebuild Kit. KTM don't sell them. You have to buy the whole MC for 4.5k. I have heard guys using parts off other bikes, anyone know which other MC's would fit the 1090's MC?
