So the radio backet keeps falling inside the dash on my '93 EG sedan. Not sure exactly what it is called but basically it's the bracket that goes inside the radio 'hole' which you would secure the HU's sleeve onto. It has always been loose from when I got the car, so I'm not sure what it's supposed to be like originally.

Any one have a pic of theirs? Or does anyone know what I'm referring to??

 

I think you mean the L shaped bracket that screws onto the dash frame and the bottom of the radio (if it's anything like the 6G one).

It should just be that simple. Look at it and make sure there are screws in all the places there should be.
