My reading of the original post, is that Kodjo is needing the stainless trim that goes with the rubber sill.
Kodjo, that piece is just a "L" shaped piece of stainless. Easy to make if you have access to a metal brake.
I happen to have that piece off of my car, so I've measured it and here are the numbers.
42 " long
6 Holes.....My guess is you already know that, as there should be 6 holes in the body
24 Gauge (.0239 thick)
The long leg is 15mm......The short leg is 6-7mm
Hope this helps
