As a way of getting some extra garage door clearance, you can prop the door up with a board (as camp2canoe suggests), or adjust the opener to get the same effect more easily, assuming you have an electric opener. Post #17 in this thread may give you some help.

Either method should help a lot with the situation you describe.
