[A/S] Adjusting door alignment

["Christopher45103" <blickcd@xxxxxxx>]

The entrance door on my '79 International is slightly out of 
alignment.  The lower corner on the latch side is barely catching on 
the threshold.  You can push the door shut all the way to close it, 
but this bends out the bottom of the door slightly.  When you look at 
the closed door from the outside, it's noticable that the gap around 
the edges is not equal all the way around.

Note that there is otherwise no improper bowing of the door, which is 
what I checked for first since that is a common problem.

I checked to see if there was any slop in the hinges but there is 
none.  It appears that the weight of the door has gradually pulled it 
out of alignment with the the top hinge over the years.

The service manual only has instructions for removing the door, which 
involves drilling out pop rivets on the inner door skins and removing 
nuts from the hinges inside the exposed door cavity.

I assume that like a car door, the holes in the door are slotted and 
it will just be a matter of loosening the nuts and retightening after 
a second person repositions the door.  I also assume that this will 
require some trial and error to get it right.

Just wondering if anyone has done this before, and if my assumptions 
are correct.  Any tips are also appreciated.

Thanks,
Christopher
