Rocker panel molding removal, how??

Depends on the year............Most models had a spring clip with a top and bottom spring wire.....a tool is inserted in the bottom under the molding, and slid along to release the wire from hugging the edge of the molding.....I used to make tools by bending a little hook on the tip of a slender screwdriver......very short hook, at 90 degrees or a hair more. Usually the spring wire would pop out from under the molding...sometimes had to be coaxed. I'm pretty sure that there was a special factory tool for these.

Once the bottom wires are released and hanging out of the bottom of the molding, you just carefully lift the molding until the top is off it's spring wires.

Later models used some nylon plastic snaps that were the full width of the moldings......you have to gently pry the bottom edges off the clip.

I've also seen them mixed and matched and cobbed........be careful.
