Product review (5 stars): Brilliant!
Not only was this one of the fastest repairs I have done, but it is by far the cheapest ($1.30).  These worked great in an old Kenmore washer.  Initially, I thought it was good when i found the agitator assembly for only ~$20, but a little more searching, and I found the dogs, which is all I needed.  Then, i found them here and got them in just a few days for about the cost of a stamp.
