Bob,
I just did mine on my duet dryer. I had to remove the door, then remove the door inside metal piece, then swap sides on the hinge and swap sides on a couple (two or three) plastic pieces. In total, I had to remove and replace 5 door hinge screws and about a dozen other screws. None of the screws were in very tight. I would recommend being very systematic on what screws and pieces came from (and go to) where.
