Neither the FAM or Shop Manual specify the gap at the rear of the door. They do call for 1/8" +/-1/16" gap at the hinge post. As long as the door closes without rubbing, and the gap is even, you're probably OK. I can't tell from you picture, but it looks like your hinge side gap is pretty small, especially at the top of your patch panel. I would concentrate on getting that correct first, then deal with the rear gap, adjusting so it doesn't rub.
