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

It's your radio mounting bracket, the sloted part goes on the radio and the end to the dash frame.
