trim question on 69 Dart

Is it the piece that covers the pinch weld from the sill plate up to the window. If that's what you are talkin about then it is a colored vinyl piece that just slips over the pinch weld. Someone may have a picture. These were used on lots of different applications. so you may be able to find some in the boneyard. just cut to length. I think even brand X cars may have some.
