Clutch components? (4)
I believe the answer is:
eggs
'clutch components?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eggs that I've seen before include "Bacon's partners" , "Reproductive parts" , "Don't teach your grandmother to suck --" , "Wherein soldiers enter" , "Don't put all these in one basket" .)
