1969 dart wheel well trim

I bought new trim at Carlisle and went to install it last night and non of the predrilled holes line up. I can clamp the new trim on and drill new holes in the car or mark the old holes through the back with a marker and drill new holes in the trim?

Which way should I go? I hate to put extra holes in the car but that may look better once installed because the trim won't look like swiss cheese.
