110 rear wheel bearing kits - quickie

hi
looking to get rear wheel bearing kits for my '87 110 station wagon with rear drums - searching and looking at Busters thread, there appears to be two seals - inner and outer - but the kits i've seen only have an inner seal listed.
even for the 83 onwards 110's - any kits have both seals or what is outer seal that i need to order separately please?
Thanks
my DS rear wheel is being covered in oil so i need to sort out the leak, assume from the paper gasket but thought i'd check and change bearing as well and check drive shaft/flange for wear while i'm at it. oil only outside not going into drum.

outer seal is frc8222

thanks!
i have removed drive flange and it's lunched, surprised the remaining part of the teeth haven't sheared off in the 500miles i've done since i got it last week. emergency replacement tomorrow me thinks.
what's best kit - are the "heavy duty" kits worth the bother - do the nuts rather than the standard caps keep the oil in any better?
my drive shaft teeth looked ok - for now - looked like the flange was sacrificial - or made of chocolate...
seen kits on island 4x4 that seem ok, might go for that...

Given the age of the vehicle, I assume it's covered plenty of miles. I had the same issue at 210k, and just fitted standard replacements. I guess it depends on how many miles, and what type of driving you plan to do. I expect the replacements to last 100k of normal road/light off road. Of course the heavy duty ones are shiney...

yay, thanks all, once i got the correct "thicker" flanges from the Indy - who supplied the thin ones despite having my reg, vin number and being tod that i had drumson the bback - i now havae a landy with no horrible clunk on take up of drive and i don't fear the drive flange being stripped leaving me in the middle of nowhere
and i can put my 200tdi to full power
wondering whether to have a look at the front pair now, just to be sure and quite easy job too.
next to clean the intercooler and flush radiator/cooling system for winter will have to try and upload pics on newbies thread if it's easy and when i have pics.
feeling a bit prouder now it's more mechanically sorted - though cosmetically challenged - that can wait a bit - though new door hinges are a must
i want some rust proof td5 updated ones and the only ones i've found are SP Landrover - anyone used these? mine are rusty as hell and pins knackered so doors dropped and can put fingers in between seal
it's my daily at mo so be nice to get bit of the (unnecessary)draughts down...
