GV Rear Axle should be 22mm and 21mm nut , but also get 20mm and 23mm as Korea did change the axles even on their bigger GV bikes.
Torque Specs for rear axle bar = About 60-70ft lbs max (Use 50-60ft lbs & double check its safe) use online converters of FT LBS TO NM if your torque wench doesn’t show FT LBS markings.
