Remove the striker post. Get a jack and a block of wood - I use a floor jack for cars, but need to use my high lift for bronco doors. Install the doors loosely at the hinges and close it. Since the striker is removed you can see how everything lines up. If it is not to your liking, use the jack and block of wood to move the door up or to support the door as you loosen the hinges and move it slightly in the direction you need to.
Be forewarned, you are probably going to have to loosen and adjust the hinges several times and jack the doors up and down several times. Moving the hinge one way to fix something that is off can and will make another part of the door off. If you are trying to get the gaps and body lines perfect, you are going to be there for a while. It's sometimes better to split the difference and just be happy with as close as you can get it.
Does it sound like I hate hanging doors %)
You are going to have further problems with the lift off hinges. Since those hinges need to be in alignment to be able to remove the doors, there is no guarantee that you will be able to get your gaps and body lines accurate and still be able to lift the doors off. If the two hinges are adjusted too far out of alignment in order for the doors to look right, that will act as a binding point on the hinges and they won't lift off.
