I'm afraid your friend is in for some serious transmission work.  The TINY 
screw thread holds the input shaft in place, but that's all.  The torque is 
transmitted by the spline on the outside.  The two shafts are coupled by 
means of an internally splined sleeve that must be slid over the two shafts 
AFTER they are screwed together.  This sleeve also happens to have one of 
the gears involved in reverse on its outside; I suspect your friend has been 
missing reverse for awhile.

It is just POSSIBLE that the input shaft, less the screw, could be pushed 
straight back into the gearbox and it might mate up with the coupling well 
enough to transmit torque, but at the very least there is now a loose 
circlip in the differential, maybe a loose reverse gear pinion.  I would 
estimate the chances of great transmission damage to be 100% if he tries to 
drive it any significant # of miles.

It should be towed, with the rear wheels off the ground, to a place where 
the left side cover can be pulled off and these parts put back in place.  It 
is likely that some parts are already damaged, or even possible that he 
already  needs a new gearbox.

If the input shaft came out with the circlip still on it and the screw 
inside it is just broken off, then it should be possible to remove the screw 
fragment and just slide the input shaft back into place inside the reverse 
gear pinion sleeve.  The engine will hold things in place until the next 
time it is removed.  If he can't seem to find the sleeve to slide into, then 
the pinion sleeve has probably already fallen into the differential and it 
will be necessary to open the tranny to put it back into place.

Removing the left side cover is exciting, but not that hard (drain the fluid 
first!) if 68 is IRS.  If 68 buses were still swing axle, then this is a BIG!!!
job.  My condolences.

Wish him luck.
