Pull-a-part on Buford Hwy just north of 4wheel parts. There's another one in Conley. check the website if there's a particular vehicle you're looking for. Saves mucho time trying to do it when you get there fighting the messicans.
I went to the one South of the city (by the airport and dump) Found a perfect '75 Celica in WAY better shape than mine. I should have bought the entire car (it was nearly complete) Other than that, nothing good. Every Toyota was missing it's drivetrain.
