Ok these first two pics are from a stock truck underhood belonging to Davis Chevy and you can see how the shroud fits up nice and close. Notice the bar that runs across the top of the radiator from tank to tank. The shroud fits up against it good.
Then the next two pics are of my 4 row rad and stock shroud and the poor fit. That top bar is wider on mine not allowing the shroud to fit up close. Look anything like yours?
What I did on mine was cut the shroud all around where it contacted the rad between the mounting ears. Kind of hard to explain but maybe you can tell by pics as it is now. I'll get back with those.
