Hub Nut Socket Size

[Tatey]

I think its the hub nut anyway. Its the massive nuts in the middle of the rear drums (HandyAndy very kindly picked up and dropped off the majority of my donor parts on saturday)

Would anyone be able to tell me the socket size required to remove them? Also what would be the best way to remove them bearing in mind the rear sub assembly (no idea if thats wat its actually called) has been removed from the donor.

What can i say, im new to this game and you have to start somewhere . So feel free to correct me on anything, any help will be much appreciated
