The last couple if radiators that I have replaced in theses trucks were replaced with spectra premium radiators from rock auto. They are aluminum, with plastic side tanks, but I haven't had any problems with leaks, and they cool way better than the ones they replaced. I hate draining antifreeze, so when I have too, I replace all the hoses, the water pump, and thermostat. The parts are cheap for these old trucks.
