1931 Murray fordor rear door ?

[linkpin]

Hello


I just got a 1931 Murray fordor the rear door hinges were haphazardly screwed into the wood with modern screws. They do not fit or work well. I removed a door and it revealed only one thru hole in the for the top hinge in the wood and it does not seem to be in the correct location. Any one have measurements or a procedure to locate them correctly



Thanks
