Homemade fan shroud lets see them

As I take a-body (for my 67 Dart)are hard to find originals, and the reproductions are junk, correct? I plan on adding the classic air condtioning and will therefor want to update my fan and add a shroud, correct? I have made my own shroud for circle track cars before but they looked like, well homemade shrouds. In one of the back sheds is an old window fan, and everytime I see it I think that it would be the makings for a shroud. Anyone have any homemade shrouds, and would like to share pcitures?
Thanks
