Does anyone know if there is a source to purchase reproduction lower front door window sash channels for 55 Coupe De Villes. The brackets on mine broke where it was welded to the channel and I took it apart to re-weld them. Once apart, the bottom of the channel has a lot of rust holes and this is where the spot welds broke. I can weld mine on still but it will be weak at best and I will be doing it again down the road.
