Both are 30-31 because of the apron cut on the front. It is deep and has a flat area at the top.
The right one is coupe and it appears to have a hole for a rumble step. It would fit all 30-31 coupe, roadster, cabriolet, and narrow bed pickup.
The left is probably also coupe etc, but something is wrong as it does not have a flat edge where it mounts to the body. A sedan fender would be substantially thinner at the top, this fender looks to be a modified coupe fender- but I could be wrong.
