Radiator for the flatty in the 31 A shell

I am ready to spring for probably the most expensive part of the build, I dont want to skimp on the radiator & want to find a bolt in for the original 31 shell & will be running the 50 flathead V8, I understand its going to be a chunk of $ so I only want to do it once, any leads?

 

Had an aluminum one built for my 31 with a flattie. Around $600. You can get one made to order from Walker(copper).

I'd have to say Walker but some folks I know swear by various makers of welded aluminum radiators.

 

I'd rather use a copper for the original appearance, anybody here a dealer for Walker?
