Cooling Issue - 1964 Dart GT - 273 with automatic and A/C

slantsixdan I'm new to Mopar (my experience is with Datsun Roadsters and Karmann Ghias), so I'm open to recommendations for good vendors, especially one selling accurate reproduction radiators. I'd like nothing more than to get rid of that ugly aluminum rad and have a more stock looking rad. It mocks me every time I open the hood, lol. Can you recommend a radiator vendor?

GlenRay in Wisconsin is the Cadillac of MOPAR radiators. You won’t find better quality, better customer service or better people anywhere…. But you will pay for it. Bob probably has the correct tanks (since I gave him an early A V8 core recently) and can build you a 4 core HD radiator. It may or may not help. Our 66 with a V8 with AC and a shield struggles in the desert once it get over 95F as well. And that is with aluminum heads, GlenRay 4 core original radiator and every trick in the book. These are only 22” radiators and never really designed with AC in mind.
