Putting doors back on, any tips?

I got a Mopar buddy to help temporarily install and align my sedan doors to my sedan delivery conversion. Since the original wagon doors had a nice alignment with the original hinges bolted to the body, I elected to leave them installed. The new sedan driver’s door practically fell in place. On the passenger door today we futzed with it for over an hour till we were satisfied with the alignment and gaps. Bear in mind I am replacing the wagon’s B pillar with a 2 door sedan B pillar and between the door and the B pillar, it took awhile.
