upper "hold-opens" will be hard to find, been a number of folks over time here looking for them - need the covers for your top hinges too, where
the check arm mounts ....
there's a small striker
at the top for the driverside door, which has a latch mechanism that sticks out the top, and another striker
at the bottom for the handled door ...
the main door handle and and
it's latch are available new, they're the same as the pass side door [well, close enough] and the striker for that is mounted on the other door edge ....
also a unique
license holder/light you won't find
I don't much like the clamshell rear myself, but I think you should keep searching for what you need for yours and skip different frustrations

also the
center stop light you have on it is a very desireable rare piece if it's complete and functional
