Projects HELP - Locating 1935 Buick VIN number

Were trying to find the location of the VIN number on a 1935 Buick 40 Series 4 door sedan survivor ​

 

try under the passenger seat nailed to the floor.

 

The one on my '34 coupe is on the frame by the steering gear. A piece of sheet metal 1/2 " wide riveted
to side of frame.
