I ordered the parts and got on YOUTUBE to watch a video of how to take off the old part and put on the new part. To my surprise, the adjuster kit had gone through a design change which is why I had to go on YOUTUBE to see how to take off the old part and then assemble and put on the new part.
This probably took about a half-hour to assemble. Actually, my husband was doing one side as I was doing the other and this worked quite nicely.
We had to use a star wrench from our Ring Doorbell on the screws.
