1994 Pontiac Grand Am Radiator replacement problem

I cannot find the correct radiator for this car! There is a special transmission attachment that is a mystery to all auto parts stores and people. This is a 4Cyl, 2.3L, submodel SE, 4 door. Local junkyards do not have this car. Can anyone help me?

This should not be a difficult problem to solve. Any decent aftermarket radiator will have all necessary hardware to install it. If all else fails, you could use barbed fittings and rubber hose to make it work. Could you post a picture of the ‘special transmission attachment?’ I’m curious.

So am I. Pics please.
