I may have another option for you, but there is not a platform-style bike rack that will mount to the bumper of your 1953 Ford Mainline.
Since there is not a custom fit trailer hitch receiver for your 1953 Ford Mainline, you would need to have a trailer hitch fabricated to fit your vehicle. Once the hitch is installed you can use a platform bike rack like the Swagman XC 2-Bike Rack Platform Style # S64650.
