<VV> Convertible doors...

[Secular]

  Hi:

  I'm trying to help a friend restore a very nice running 65 Corsa Convertible (ummmm...blind leading a blind) - the doors are sagging and do not close "nonviolently". 

  The car has minimal rust (mainly surface genre). All 4 weights are there, it's complete and the engine/tranny are in excellent shape (we had to rebuild the carbs). 

  Underneath, it's very solid. Floor pans, etc...

  Why are the doors sagging? Is there a way to adjust them? 

  Regards,


  Tony
