8.75 suregrip gear swap questions

Guys, i got a 8.75 third member going to swap ring and pinion on to a suregrip cone unit. I was reading that taking the main caps on the carrier off one side is left hand thread and the other is right hand thread? is it good to mark everything to identiy which way the caps went on? Also any tips and tricks to removing the ring gears? the gear set will be set up afterwards, Thanks Again!
