Photos of rear window opening and front bumper mounts. 1941 or 1942+ cab ??? Do I need metal frame & gasket or just '46 style rubber gasket ?

Bumper mounts at front end ... need brackets, but which ones ? 1/2, 3/4 ton ? This is a 1941 "I believe AN" with the 9' open express box. I would like to mount the larger 1.5 ton style bumper or build my own.
