-Please- don't use a gate hinge.
Trust me, I build hotrods and do restoration work for a living, those aren't strong enough.
The speedway hinges work great and look the part. Plus, you can probably go earn $100.00 in the time you will take to modify a flimsy door hinge.

Good luck with your build.
Almost forgot a small tip for you. Even 1930s car doors had a bit of curve to them.
When you go to hang the door, mark out the spots for the hinges on the door, then drive the pins out of the hinges and run a piece of drill rod the same size as the hinge pins through both (or all three) hinges on the door, in place of the pins.
Now drill the mounting holes and mount all the hinges at the same time with the rod running through all three.
This keeps the pins in a straight line and will keep the hinges from binding up when you open and close the door.
This is really important when converting to suicide doors.
Also, if for some reason you use suicide doors, be sure to install a deadbolt mechanism to ensure that the door can't be accidentally opened. I've seen the mess it makes of the car.
