Grab a car part (6)
I believe the answer is:
clutch
I believe this clue is a double definition.
'grab' is the first definition.
(thesaurus)
'a car part' is the second definition.
('clutch' is part of 'car')
(Other definitions for clutch that I've seen before include "Quantity of eggs: cling to" , "Grasp - eggs laid in nest" , "Hold tight to the eggs" , "Seize - batch of eggs in single nest" , "Grasp, hold firmly" .)
