what part of the body makes the most sense to start on

With the car on its wheels level lthe rocers front to rear. Align doors with out latches. Make sure whent they are in the closed position they align perfect. .


Sorry for some dumb questions here, but i'm a little confused with some of these steps.

I don't know how to align doors without latches.
- I installed the doors back in place to ensure they close properly after placing the car on 4 stands.

when in closed position they align perfect.
- well, I have replacement doors and I dont' know what perfect means on a 40 year old car. I'd like them to be perfect. They don't seem to have any, if much, wobble in them when open. Below are some photo's showing the gaps between rear quarter and rockers...

Passenger: (it is a tight looking fit on the bottom corner where the quarter/rocker/door meets.. no issues closing door)







driver:








If anything, on the driver side, the door does set 'out' from the rocker a bit, as if it's bowed out or maybe the rocker is just in that bad of shape. Not really visible it seems in the photo i guess.
