The part numbers shown in the 1929-1950 Master Parts Catalog for 1941-1946 1/2 ton and 3/4 trucks are:
Left front--3664961
Right front--3664962
I have been unable to get to my fenders. Maybe one of the other guys that has more ready access can help with measurements.
Your question may reach a wider audience by being re-posted in the Truck or Body etc., forums here in Chat.
