I bought a radiator for my '86 Brat from Kragen Auto Parts for $150. I heard you can find them online for $100 or $120... but i didnt want to wait for delivery.
Just give them the year and model of your car. Tell them if its manual or automatic as well.

I don't know the '83 GL, so this is only generic advise, but I have seen this on three vehicles over the years.
If it doesn't overheat at idle or low speed, but does at higher speeds, check the lower radiator hose. Many vehicles are supposed to have an anti-collapse spring in the lower hose, so that when the engine is revved and the pump is pulling hard, the lower hose doesn't collapse. You can check this easily: with a hot engine (coolant up to temp), open hood and watch the lower hose while opening the throttle with one hand. Rev it up to 3-4k or so and hold it there for five seconds or so. Hose should not change in diameter appreciably. If you see it start to flatten out, you've found your problem.
I've had three cars over the years (non-Subarus) with the springs either missing or rusted out (from lack of regular coolant changes -- every two year!).
