Door assembly

[twotrucks]

Door jambs, door hoops and cab jambs and roof has been painted. Empty doors assembled to cab. Wondering if doors will sag when glass in put back in?
Can glass, wing window, and window regulator be put in now and after painting outside will I be able to install door lock, handle, mirror and window sweeps? Or should door assembly be put off till all painting finished? Would like to put fenders back on and not have to worry about re-adjusting doors.

I would paint the doors, Hang the doors and then add the glass and such. Adjust to the door frame as needed. Then install fenders.
