not the same at all. chevelle is on the rocker exclusively and the Beaumont is a 4 part extrusion with no 'ribs' in it that goes along the fender, door, rear quarter behind door, and then there is a tail pc on the rear of the quarter. they are so hard to find that most will end up putting the chevelle rocker trim or nothing on. DT stainless can reproduce them for just over 2k, and they are pretty fantastic quality and very very tough compared the originals.
