Usually... in front of the steering box. Ford did stamp a number on the transmission/bell housing. Not on the motor as they were in and out and switched.
I did some research and if I'm right, there were no vin numbers before 1954. However, there was a number stamped on the plate/tag mounted on the firewall and sure enough, that is what I have with a number on it. The insurance company wouldn't accept that at first but now they do. Thank you everyone for helping. Now back to wiring the rod !
