The latch to the soap dispenser was broken. I was able to loosen the remainder of the latch some with pliers but pieces of it kept breaking off due to age. I was able to get it off with removing the retainer on the back of the door panel. It took a couple of tries to get the new latch and retainer on but I got it done. The most difficult part of replacing the spray arm and tube was getting the hangers-on and making sure they were in the right direction. Everything else was easy.
