Chev radiator fan

[Wayne Henderson]

Which fan is correct for a military chev 216 fitted to a 1942 C15.?
The fan for the radiator on my restoration is a 6 blade version and I thought this was a modification post war/farmer.

I always thought that the blitz had a 4 blade fan but this seems to be correct only on long nose civillian type chev trucks.

The radiator shroud on my vehicle has been cut to allow for the wider fan.
Maybe the radiator is from another model chev as it is the only radiator fan shroud I have seen on a Chev blitz.

Ideas or comments most welcome.
