This part worked perfectly, but it wasn't easy to replace. The nuts holding it to the mower are in a very tight place and difficult to reach/turn. You can only turn each nut 1/6th turn at a time with an open end wrench, so you can't be impatient. The biggest challenge is getting the nuts started on the new studs. I used the open end wrench to hold the nut in place while pushing the stud all the way in. This used the partition behind the assembly to keep the nut in place long enough to remove the wrench and spin the nut with one finger until the threads caught. It was rather tricky.
