That is about as easy a car as you will get to do it. Now, if memory serves me the doors on that car swing OUT on the outside of the front fender like the trucks of that year do right? If they do, you don't even have to buy hinges, just put the hinges on the rear and move the latch to the front. Though, I would use a modern "bear claw".
The door is strong yet light, so little reinforcment would be needed. The quarter as well will need little reinforcement.
That would be a pretty easy one to do.
Click on the link below and you will see a diagram of some hinge theory. The hinge pin needs to be positioned as close as possible to the skin on the quarter. As you can see in the "B" diagram the hinge being back too far brings the arch in and the door is actually moving back as it moves out causing clearance problems with the door to quarter.
If I am correct the door moves out over the fender on your car, if it does you can see that the hinge pin is pretty close to the fender skin. Repeat this on the back and you shouldn't have a problem.
You will have to add some reinforcment to those hinges, but on that car it is pretty straight forward.
