45/46/47 Ford Pick ID number frame location

I have a 45/46/47 Ford Pick up and would like to find the ID number on the frame. Does anyone know where it is located? Is it in more than one location on the frame?

Thanks

 

take a look at www.ford-trucks.com
they have a forum for those year pickups.

 

On top of frame on driver's side about 8 inches ahead of front cab mount. That's one location ...I'm sure there are more. On my 48 ford Coupe its in about the same location , but it also appears on top of the frame midway between the front and rear axles , and again over the rear axle . Hope this helps.
