i would love for my 1982 subaru brat to not get hot when im on the highway, what kind of after market radiator can i get to were it stays at a normal temp all the time?

I would start with checking you thermostat. The stock radiator is plenty to keep your brat cool, even moreso on the highway. Also check you coolant and water pump. Maybe your radiator is dirty...

First you need to verify your temp gauge is even accurate. They are notoriously not. You know nothing yet and jumping right to replacing the radiator is a huge mistake.
