Feeling dense- missing two letters. This looked impossible at first, but this poor Yank made a lucky guess early on. I'm just not getting 45a, however: EX-giant (4). This may have to do with 32d: Money, sort that's not special, finally (6); I see what the answer must be but am missing the wordplay (I gather that "that's" is IE, but don't see how it gets stuck on the end). Is money not the definition? Hints, anyone? Everything else is perfectly clear. Braced for embarrassment.
