I need a plastic fan blade, approx 7inch dia with a 3.5 inch center
about .75 inch thick. I'll drill my own monthing holes for it.

background.
I need to replace the hydrostatic cooling fan in my cub cadet 383
garden tractor, part number 759-3273 and about $30 retail. I remember
seeing(somewhere online!) fans of this size for less than $10 but
cannot find the source anymore.
