According to Autozone's own website, that part # corresponds to an aluminum radiator with plastic tank sides. Not copper.

Coincidentally, I just happened to be in Autozone yesterday picking up a few items related to this area of my build and inquired about a copper 4 core radiator as that's what my truck calls for. I was told Autozone does not carry Spectra's copper 4 core version. Aluminum with plastic tanks is what they offered me at a cost of $183. $165 delivered is still a good deal for this but according to the part # it's not copper.
Here it is from

They want $216 so $165 delivered is a great deal.
