NOS Radiator help

[sullyscout77]

Need help identifying application for this NOS, (still in the box), radiator. I saw the top hose connection and that it had the tranny coolant line ports just looking in from top of box and jumped on it for my '77 with TF727. Yesterday, when I finally needed it, pulled it from the box and to my surprise, wrong application.
First pic shows my radiator with mtg flanges on the engine side.
Second pic shows my radiator lower hose connection which comes straight out.
Third pic shows Mystery Radiator with mtg flanges on the opposite side.
Fourth Pic shows angled lower hose connection on Mystery Radiator.
Fifth shows P/N on Mystery Radiator, #385485 C2.
Can anyone help identify application?
Thanks in advance;
