36 body to frame. Which holes?

[36coupe]

I am putting a 36 five window body on a 36 frame.
Does the cowl bolt to the front holes or the rear holes. It seems it needs to go to the front ones.
For the radiator I am thinking it should go to the rear holes, is this correct?
Should the rear two bumper brackets be bolted to the frame before putting the body on? Or does this matter?
