How to remove 1953 oldsmobile radio from dash

I think I remember. Do this, pull the knobs off and you'll see 2 9/16s nuts use a deep well socket to loosen but don't remove look under the dash for the brace on the rear of the radio, remove the brace then the nuts. The radio comes out the back and you may have to remove heater control cables in order to get it out. I hope this helps. Take care.
