Did the 65 6 cyl have a radiator shroud

To answer the OP's original question, whether or not a car had a fan shroud would depend on whether or not the car had HD cooling. HD cooling was mandatory with factory A/C and the towing package. It was also available separately.

Neither the V-8 nor /6 shrouds is symetrical with the radiator. I can not confirm this but have heard that the V-8 shroud will work on the /6 if it is rotated 180 degrees.
