Help needed! Best cooking radiator for 67 Dart

Hey all! Need help with what is the best direct fit cooling radiator to put in my 67 Dart GT convertible. Just put in a 69 340 mild build engine, but the old radiator can’t hack it anymore. Car is in Florida, so no worries about running too cold.

if the old one is original, save it, sell it or trade it. '67 is unique and some people will want it just for parts.
