The agitator wouldn't turn.

The part came in the mail. We (my daughter(12 years old) and I) opened the box. Took the part out and measured it (the description didn't fit the requirements). It turned out to be the correct part. My daughter undid the retaining bolt and pulled out the old agitator. We compared the the parts side by side, and everything matched. We put the new part in, aligned the splines, and reinstalled the retaining bolt. Everything went perfectly.

Thanks,
