1975 Plymouth Brougham 4 dr Valiant

I don’t know if I can remove them without damaging them either.
The ones I got were pulled up and tugged on and was the reason they got arch bent. When I put them on my Valiant and then decided to remove them because of the exercise damage, I took a small flathead at the outside of the trim after I got under it I used a plastic trim tool and got it under and slid up along the trim and it comes off without bending. I think then they installed them they hooked them on one side and pushed over the other side till they clicked.
