Anyone built or found a fan shroud to fit champion radiator??????

Champion told me their twin 10 inch fans would fit on their 22 inch 4 core radiator with their shroud. And it would fit fine in my '72 Dart 360 block. Well it does not even come close.
It did not clear the pulleys at all. I had to zip tie the fans to the radiator. I measured before I ordered and told them, they said it would work but nope. They said to ship it back (at my expense) and they would perhaps try something else. Shipping cost from Florida to California is quite expensive.
Now I too must make something else work.
I am not mad, but man am I disappointed.
