A good idea would be to write the clue and give the letters which you have and the spaces - like other entries on the site do - then people who don't have the crossword in front of them can try to offer help
..."only a difference of one letter anyway!" are you serious? lol.
i must revolt (an anagram of trevor? - close enough i s'pose) against that, it shows a lack of appreciation for the construction of the clue.
