Hi guys, Unfortunately genuine parts are pricey but the qaulity is really good. It may only be around £100 for the build depending on what needs replaced. All bearings would also be inspected and fresh sealer to reseal the box. Never had any issues with boxes I have built, and have built many manufacturers. Pm me if you are interested, @ ollie Ryan, if postage can be sorted a rebuild is no problem, pm me if interested buddy Gary
