That crossmember was fitted to the C15A whether a winch was fitted or not.
The F15A did not have that crossmember. Fords factory fitted with winches also had a double rear crossmember setup with larger fishplates.

Not sure about other Chev wheelbase models, perhaps a Chev expert can chime in here.
