Hot Rods Radiator equivalent

Is there an online resource where you can look up a radiator of equivalent size to yours?

Reason for question - my radiator is on it's last legs and I'd like to get a nice aluminum one some time in the future (i.e. when I can afford it) but in the meantime, I'm looking for a used one to tide me over but I don't know which other rads would fit.

Any advice appreciated.

 

...And this would be for what?

 

Here's something I posted some time ago:

 

Yeah, it would help if we knew what car it was for??

Doc.

 

1949 Ford sedan, passenger car with a Chevy 350 engine putting out about 225hp

 

Why the hell does an online listing of radiators cross referenced by size matter what car its for?
I haven't seen one posted online, but have seen it at my local radiator shop in hard copy.

 

http://www.usradiator.com/radiators.html if you want to search though the various makes and models.
Back in the 70's a lot of guys were using Mopar radiators in various early cars with later engines.

 

Thank you all for the hints and tips. Much appreciated!
