63-4-5? Vin Location
 

Someone left me high and dry, When they abandond an old
1963-65 Ford F-250, on the property, when they moved out 4 years ago. Where is the vin on this thing? The doors are gone, It has no motor. No vin on the dash that I can find.
Looked on the firewall. Any ideas? I need it to get rid of it
thanks
