Male lead swapping parts of Charlie and good man in racy vehicle
I believe the answer is:
stock car
'male lead swapping parts of charlie' is the definition.
I can't tell whether this defines the answer.
'good man in racy vehicle' is the wordplay.
'good man' becomes 's'.
'in racy' becomes 'tock' (I can't explain this - if you can you should believe this answer much more).
'vehicle' becomes 'car' (car is a kind of vehicle).
's'+'tock'+'car'='STOCK-CAR'
'and' is the link.
Can you help me to learn more?
(Other definitions for stock car that I've seen before include "Production-line vehicle modified for racing" , "production saloon" , "Modified motor for racing and ramming" , "Production vehicle used in racing" , "Vehicle adapted for bumping races" .)
