Replacing rear license plate mount unit

How do you remove and replace the rear license plate mount assembly on 2001 4runner

 

Do you mean to tell me no one has ever removed and replaced the entire assembly ..... what's the secret !!!!!

 

Remove the inner plastic trim and it will expose another steel plate with 10 bolts or so and then the panel is accesible. I've pulled mine off.

 

Thanks , did you have the rear window up or down ??????
