1941 Dodge Coupe Radiator same as Plymouth

[miker]

I just got a call from the radiator man letting me know that my stock radiator for my 41 dodge 3w coupe is junk.  I see that Champion sells an aluminum unit but only lists it for Plymouth and the later model ('49) seems to be a closer fit dimension wise.  Anyone know if a 41 plymouth and dodge car used the same radiator and does anyone have experience with one of these Champion units.  

 

Thanks in advance.

Does the site give any specs on the rad size? I have a 42 dodge rad, I could see about measuring it if it helps
