Yep. First one is 1959 Elky. Last couple are for 1940 Plymouth 2dr sedan. Bare wood construction is rear seat, finished one is front door. All ae constructed the same way. Built with 2x4 wood, topped with 1/2" plywood, topped with 3/4" foam, covered in Naugahyde. Figure out a way to tie into the factory arm rest mounts. On the Elky I used long screws from the outside that screw into the factory capture nuts. Plymouth front, I screwed a length of 1 1/2" angle iron bolted to factory capture nuts then a couple of bolts down thru the plywood into the top of the angle. The top piece of 1/2" plywood snaps into the arm rest wood box with panel fasteners. It is covered with foam rubber and upholstery. Finished rear arm rests. Get creative with the wood boxes.
