If the shroud isn't a "show piece" you can always "egg" the holes and put a washer between the shroud and the screw head, then set the shroud where you want. That's what I had to do with mine.

This is assuming the water pump is the issue and not the fan diameter.

I went to a clutch fan which is definitely from a later model, and my shroud worked with a little adjustment. I did use a short water pump in both applications though.
