The one for a cross flow does not have a hole for the radiator cap and the one for the down flow has a hole where the cap is located. I believe (but not 100% sure) the one with the hole will also work for the cross flow but would not be “correct”
No shroud in the 61-63 f-85 models. I did see a car that had a very nice looking home made one. I did not have a camera or I would have taken a picture of it.
