body parts.

[swampgirl]

Can anyone help please? I just can't my head around these two clues. I have thought and thought about them but drawn a blank. Any help is most appreciated.
43.
Has knowledge, I hear, of disreputable bar. (8)

24. Sty looks awful (5)

43 Nosedive would fit the clue

[swampgirl]

Thanks, I got that but don't know how that would fit as a body part?

[squarebear]

Because it's got NOSE in it.

Has 24 definitely only got 5 letters ?
Cos it could be eyesore ?
