Technical crank adaptor for chevy small block in a 1939 Ford

I just bought a 1939 Ford Deluxe Coupe - old 1964 Chevy 327 and 4 speed with a Columbia 2 speed rear end. The stock radiator was adapted for 4 blade chevy fan. This radiator is spaced up about 4 or 5 inches from stock mounting on the frame - to center up with the cooling fan. I want to keep vintage look and not run an elect . cooling fan and in the 1980's 40's Fat Stuff sold an adaptor to mount the chevy manual fan on the chevy crank - like the flat heads. 40's Fat Stuff has not stocked them since the 1980's - and info on location one?
Thanks.

 

i'd check with Speedway......if they don't have it: a piece of steel + lathe=adapter

 

I did not see in Speedway. I wish I had a lathe - I have the welding covered - but no real machining equipment .
