How to remove Limited side lower body cladding?
 

My sliding doors and rear fenders immediately in front of the rear wheel are rusting.

Since a local junk yard is willing to sell me just the side lower body cladding on a Limited sitting in their yard, I'm thinking of putting them on my SE to cover up the rust.

The question is, how do I remove these from the junk yard Limited without damaging them?

Thanks,
Jim
