1946 Fleetmaster help

[46fleetmaster]

Hi, 

I am new to this forum and wanted to see if anyone would be able to give me some advice. my husband is trying to restore a 1946 Chevy Fleetmaster and needs to get a new radiator. I have ordered it 3 times and each time I get the same one which is different than what I have been ordering. I have attached the pictures so you can see what I mean. The top tube is not centered and the bottom one is not curved. If someone have any advice as to where I can buy the one that I need, or why I keep receiving the other one, it would be greatly appreciated. 

 

Thank you!
