Can someone Identify this Power Steering Cooler

Seems to have a mid 68 unless it is 78 date code. Also has the same bracket numbers (21042) as a Federal Type I have, but orientation is different. Can't find an example on google search.

My first guess is a 78 police/taxi something. I have a similar (though not identical) one that came off a late 70's police vehicle.

I have one too but the bracket is different. I think mine is from the 90`s or something.
