Tony and T-Man. With that body you can't run a newer that 32 grille shell for ANY year of the body. I believe that all, from 30 thru 41 which was the last one, all were considered the same. One that runs in Gas/Fuel Roadster is a steel '37 and was denied the use of his 37 grille shell. I still have a 30/31 grille shell and hood in my stash of stuff that I needed to prove length and sizing from many, many years ago.
As for running is Street Roadster. since Lattin has been able to run the coupe style body in the VF class this COULD be possible. Highly unlikely do to the seating but possible. . . . .JD
