Good man rebuilt a crock - for racing? (5,3)
I believe the answer is:
stock car
'racing?' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'good man rebuilt a crock' is the wordplay.
'good man' becomes 'st' (abbreviation for saint).
'rebuilt' indicates an anagram.
'a'+'crock'='acrock'
'acrock' with letters rearranged gives 'ockcar'.
'st'+'ockcar'='STOCK-CAR'
'for' is the link.
Can you help me to learn more?
(Other definitions for stock car that I've seen before include "Type of racing" , "Production-line vehicle modified for racing" , "customised vehicle" , "Modified motor for racing and ramming" , "production saloon" .)
