Somewhat along the same lines... Haven't been able to sell this monstrosity, so I wound up putting it in the garage. Had a little rack system cabinet in there. My wife bought so e new bedroom furniture, and this was in there.
Just curious, when you took it out were the tabs cut to bend back to be able to fit a single din unit in there? Mine were and they don’t look butchered. Almost a factory look. I can’t remember when those started coming out.
