So I got the radiator and Vintage Air condenser mounted onto the core support. I also got an overflow canister from a friend and fabricated a bracket to mount it. My LS swap radiator does not have provisions for automatic transmission cooling, so I have to come up with a transmission cooler. I contacted the people at Derale to ask them for help in sizing the right cooler. They told me that since I don’t have an auto trans cooler in my radiator that sizing of a primary cooler is important. They suggested that I get their PN 13960 for use as a primary cooler. It comes with 6 AN connections, 500 CFM fan and 180 degree in-line thermostat for turning on the fan. They said that this cooler can be mounted anywhere, and in any position. If I bought it I was thinking of installing it either under the bed, or horizontally up front just passed the core support. I'm not so sure that I need one with a fan. I might look for alternatives if I can find a way to mount one upfront in the core support area.
Here is info on the Derale cooler that was suggested:
