I ordered the part and it took a few days to receive it. I removed the old mullion and installed the new one in about 5 minutes. One thing though, be careful when you reinstall the new mullion and don't be too rough with it. Mine wasn't fitting in well, so I thought that I should tap down on it with my hand. Well that is fine, but I was a little too aggressive and I broke the upper hinge. They are a little fragile so be careful. Fortunately, the upper hinge on my old mullion was still good, so I removed it and put it on my new mullion. Then I reinstalled it and took a little more care lining it up. Works perfectly now, but for a second there I thought I had blown it. I also replaced my ice maker on a previous occasion. It was a snap!
