If those are the style doors you want, why not have a local metal shop fabricate them. Locally Ackerman Brothers wouldn't have any problem with them.
In fact, if you can weld, they could be a nice weekend project. Buy the tubing and sheet metal then cut and weld the frame. Cut out the sheet metal and if want the stiffing bends, clamp the metal between two pieces of angle iron and add them.
Actually, they look durn nice.
