Alternative radiator fan shroud suggestions needed..

[flathead31coupe]

I have exhausted all places on the internet to try and find a 26" fan shroud for my non a/c 340 duster.. Is there any other Mopar fan trail that will come close?Maybe with some modifications.
Suggestions needed thanks

I've heard a slant six shroud mounted upside-down works but have never tried. Maybe someone can confirm?
