Need help finding a radiator for '56 Town Panel

I am in the market for a radiator for my 1956 Dodge Town Panel 1/2 ton, it is powered by the stock flathead 6, I believe the cu. in. is 230.  I don't really want to put in a newly manufactured one but rather have an original one rebuilt.  It currently has a radiator that has a center fill, which must have been transplanted sometime in the past.  Thanks for any help, Bob
