Install the doors with both hinges attached. Just snug the bolts, don't get them real tight, as you will probably have to do a lot of aligning. Hinges on body will give you height and back and
forward movement. Get the door aligned for gap at 1/4 panel. Once that is achieved, in and out movement on the door with the hinges attached to door. It is much easier to align doors to
body and then fenders to doors. You didn't mention whether the fenders were on or off the car. And have a helper as that is a hard job to accomplish by yourself. Also tape edges to avoid
scratches. Deaden the tape by putting it on your shirt before putting it on the car. This will minimize pulling the paint if your edges weren't prepped good.
