I was pretty good at bagging stuff when I disassembled the car ( thank goodness) and these parts are labeled with this trim and snaps.

In checking a little more the well liner does not go to these.. Had a brain cramp and wondering if the front of the stainless well trim clips into these retainers as well as the snap/screws??

I am sure that these retainer/clips go there as the snap/screws ( that go through the stainless trim and the sheetmetal) need something to attach/screw into...
