Hanging An Assembly Line Door -
First, the setting: The body of the Mustang has been welded together, everything that needs to be welded on the car, has been welded on the car, mostly by spot welding. The Mustang has not been painted. All the pieces that were welded on were primed, but the welding process has burnt off some of the primer. Nothing that bolts on to the car has been bolted on.

General Discussion:
This is what I've determined.
Some background: The Ford drawing number system is organized by ?assembly line steps?. If you look at any of the Mustang Assembly Manuals, the assembly line procedures follows the Ford drawing number, with the lowest number being a starting point and the highest number being a finish point, with drawing numbers in between being "steps". Each "group" has a letter prefix, W = Weld, E = Electrical, N = Body, T = Interior; a year number follows the letter. The chassis manuals follow their own lead. Many electrical items, like harnesses, are the first items to be installed, especially the interior, as they get covered by panels, headliner, carpet, etc. Lamps, gages etc, may be connected in later steps.
An example is from the 1965 Body Manual (some of the drawings apply to both 64 1/2 and 65 Mustangs). The first sheet, N4-N5-8100, attaches the front bumper to the car after the front valence is installed. N4-N5-8110-1 attaches the fenders and hood hinges; N4-N5-8110-2 attaches the front valence, the grill ?stuff? and hood latch. All this was done after "some" of the electrical wiring was installed.
Each drawing uses "item numbers" to associate an item on a drawing to its reference information in the Bill Of Material. They are in circles (Notes are in squares). The "item numbers" are also an indication of assembly sequence; item "one"? gets installed before item "two", etc. Hardware items (and sealants sometimes) are identified by letters of the alphabet and also shown in circles. Hardware item letters are "usually" in alphabet order, A, B, C (after Z, it?s AA, AB, etc).
Exceptions are normal. A Ford drawing "standard" - isn't. Ford built cars, not drawings.
In all of the referenced assembly drawings above, the fenders were NOT attached, and the door hinges were attached to the body FIRST by the bolts called out on the drawings, with a layer of sealer in between. (The sealer may have "stuck" the hinges to their mounting surfaces loosely with the bolts not fully torqued down and made "adjusting" easier, then the bolts were torqued to spec. A San Jose assembly line worker showed me how hoods and hood hinges were "adjusted" with a rubber mallet on my 66 GT Fastback during half-time at a Super Bowl Party at my house several years back.) Then the empty doors were set into place, and attached to the upper and special lower hinges (they had a spring and a stop) with some sealer and their appropriate bolts. I remember seeing a video of a door on a Ford being installed by being "set in the door frame". There were rubber (or plastic ?) "spacers" used, two on the bottom of the door to the door sill, one (or maybe two ?) on the rear of the door to the door frame. The striker was NOT installed. The "spacers" were designed to compensate for the weight of the door innards, latch, windows and associated mechanisms, for an "empty" door. When done, the door was opened, the spacers removed and the car was ready for painting (plus additional priming first ?) to its final color, hinges and bolts included. The trunk lid, hinges and hardware was installed prior to painting as well, but that is a story for another post.
In addition to this, I stopped at a nearby body shop to swap Christmas gifts (I got a bottle of Cab) with the owner (he and I served on the same class of US Navy Destroyers) and asked him about Mustang door installation. He was unaware of the assembly line method of hinges to body first. He said he usually attached the hinges to the doors first. It's what works for him.
