Rear drive shaft circlip

I'm getting organized to attempt to change the rear drive shaft oil seals (seals ordered) , looking on rave it says to remove and replace the circlips prior to re-fitting the driveshafts back into the rear diff.

Now my question is after doing a search on here for the easiest method for changing the oil seals and reading quite a lot of threads I haven't seen mentioned the changing of the circlips is this required and if so can anyone give me the part number or a link to purchase them.

Thanks for any thoughts.
