Very easy to do stainsey,as said make sure to give each one a good tap to break the thread lock plus corrosion,which shouldn't be to hard for you,dont break the wheel :grin:i kept each centre with each barrel cos im like that lol,make sure to run a tap through all the threads before rebuild standard m7 iirc,i didn't torque mine back up just don't over tighten them! ,use thread lock.
