It has been many years since I restored a '37 pickup, like 1964-65, still have some of the left over parts.
The grille shell attaches to the front fenders at the very bottom, three bolts on each side as I recall. I recall a tab on the side of the radiator, at about the mid point that attached to the radiator support and two screws at the top that attached to the radiator.. Two quarter inch rods then attached to the top of the radiator, extending to the firewall. The grille shell attachment on the '37 is similar to the '35-36, however it is different because the shell is more massive with the grille being a part of the shell.
I still have a very nice '37 radiator, rear window molding and I believe I have some instruments.
