1968 Barracuda. Is this the stock radiator?

So, I have a long list of things to do on this car, but up front is fixing/upgrading the engine cooling system as it runs really hot. I just ordered a reproduction fan shroud thinking it would just bolt on. After doing an image search online of engine bays for other barracudas, the radiator looks very different. My limited research suggests different radiators were put on based on whether AC was installed and/or performance engines were installed.

If this isn't the stock radiator, what do you think it's from?
