Dayotn wheels spindle nut torque specs

I'm doing a brake job on my 87' 357 Pete. I was just wondering what the correct spindle nut torque is suppose to be. I was told torque the first nut to 250 ft. lbs. to set bearing and wheel seal then back nut off and reset at 50 ft. lbs. install locking washer then second nut at 50 ft. lbs. Any tips would be greatly appreciated. Thanks
