Where does this bracket go???

I dissassembled my 1970 challenger some 4 yrs ago.
I bagged and tagged all the parts but found this bracket lying loose in my box of dash parts.
It's an Aircon car and i know it goes up under the dash.....somewhere
Can anyone tell me specifically where it goes?
A pic would be even better

Rear of radio support, slot goes to a stud on the right rear, stud goes to body of dash

Thanks for that Bullitt.
Makes sense since I haven't fitted the stereo yet.
Although it surprises me the original bracket is still there as it was an aftermarket stereo in there when I got the car.
