I'm starting to think that the last things to go onto the car are the wheels and tires and that the interior, trunk and even the engine compartment is or are 95%-99% complete and that hooking up, bolting in or attaching the already in place components is all that is done after the driveline is installed. Look at these images and what's left but attaching the drive line to what is already there. The steering column attached to the steering box on the K-frame, trans linkage, throttle cable, trans kickdown linkage, leaf springs, brake hoses, etc., which to me would mean the interior and trunk were finished by this point, meaning no wheels/tires on the care to key off of for the spare.
