i have a set of EURo R side skirts in my garage, planning to install them this friday when i have some free time, my question are

do i need to go to the wreckers to pick up the missing trim to fit the euro R skirts? does EURO R skirts have their own inner trim(did not get any when i pick it up off some guy)? do i need it at all? for this installation

When I install the euroR skirt, I reused the trim that was on the original skirt. Here's a photo of the trim on the passenger euroR side skirt
