Tap? When it comes to aligning the doors, I have a large rubber flooring hammer that I'm not afraid to let loose with. The door can even be twisted by grabbing the open and and twisting against the hinges. Several times I've had the door fit perfect, only to remove them and resintall and they're out of alignment for no reason!?!
I have also hammered the A post hinge locations and/or bent the brass hinges to get everything into alignment. It amounts to whatever it takes to make it all fit...preferably before the paint goes on. You get more limited after painting.
