Rat was a dreadful typo, sorry. Should have said rest. I just can't see the correct answer that makes everything work. To fit my replacement in 6d I need an n from 35, but my answer uses both n's in what I think is an anagram although I'm not sure about the Australian being there! I now think I am one submarine short so I have to use the s. But that gives me intwins and untwins and a very spinny head!
