I’m restoring a ’57 Merc Turnpike Cruiser Convertible and the things I need most right now are rear quarters and a front driver’s side seat back. I know I can use a seat back from a two door hardtop, I’m not sure about the rear quarters. Any help would be truly appreciated
The quarters from any 57-58 2 door model will do. You may have to work on the top where the belt line is, I’m not exactly sure if the quarter ends in the cove molding area, or if it goes all the way to the belt line on these. Depending upon exactly how much you need, you might be able to cobble together 4 door ones to work, although with a Turnpike Cruiser convertible, the finished value would justify looking for the correct parts.
