Before and after of the interior - this is also AFTER hauling all the big junk out of the inside.
So after getting it all cleaned up inside and out, I threw a battery in it to see what would happen - turns out the starter grinds on the flex plate and doesn’t turn the engine over. I’m hoping this is the reason it was parked, instead of something major like the engine or transmission. If that’s all it needs, it may actually run and drive!
