My go-to DIY videos for my '83 SC is here:
https://www.youtube.com/@Dr.Garage911/videos
This channel has a few door install/adjust videos. Here is a link to the channel filtered for its "door" videos:

Give this a try, you may find something that helps you.
NOTE: videos do not have dialog, only subtitles/captions in English & Japanese.
For my '83 SC, the videos on this channel are as close to a "video version" of the "101 Projects" as I can find.
Good luck!
