It's not the way I wanted to do it, but the #$%#$ hinge bolts will not budge. The GMC maint. manual pages from 46forme advise to use a block of wood or wooden tool handle to "Spring" the hinge by closing the door on the tool... I figured if I am supposed to shut a block of wood in the door, using a cresent wrench with very even pressure had to be easier on the pillar, door etc than that...
It worked...and I don't have to do it again...
