I'm in the need for a fan blade for a 1951 235 2-ton (big stovebolt) engine. I bought one from Chevy Duty but learned this morning it is only for the 216. Help!!!

Anybody purchase a replacement from any parts dealers? I've search most of the chevy parts suppliers I know about and can't find one for a 235 from 1951. If you bought one or know what is compatable, please let me know. The engine rebuild is almost done and now I've got no fan... Sometimes it just goes that way when you've got a big truck.
