In position, for example (8)
I believe the answer is:
instance
'example' is the definition.
(I know that example can be written as instance)
'in position' is the wordplay.
'position' becomes 'stance' (stance is a kind of position).
'in'+'stance'='INSTANCE'
'for' is the link.
(Other definitions for instance that I've seen before include "Case - isn't acne (anag)" , "Exemplify" , "An insect (anag.)" , "'Example, illustration (8)'" , "Canniest (anag) - occurrence" .)
