Mission accomplished.
Realized my portable work platform courtesy of Northern Tool was the perfect height with a couple of drop clothes used for padding to support the door as unbolted the old and bolted up the new.
Was easier to detach the door from the hinge rather than the hinge from the pillar.
Swapped over the lock cylinder from old door to replacement and all is working well.
The black clip in the last few pictures dropped from behind the trim panel when I removed the panel from the old door and same thing happened when removed panel from replacement door.
Where the hell does that clip go and what is it’s function.

Thanks to those who provided suggestions.
The list continues:
*Valve cover gaskets
*LBJ with inner & outer tie rod ends
*Rear axle bearing, seals and new backing plates for the brakes
