I don't have a clear photo of the radiator in the one I had, sorry.
But, it was a '72 Duster with a healthy RB 512.
Champion 26" in the stock 22" opening.
With a direct-drive stock fan, a shroud, and a little smaller water pump pulley I had, the thing always ran 160-170.
Ran a separate ATF cooler.
Hottest conditions were mid-80s in traffic here, still never topped 170.
Car is now in Florida, no reports of it running hot.
