Product review (5 stars): These are great replacement parts
After I found out what they were called and their part number from the Sears website I found these here from SupplyEdge.  I picked these for the consistently above average reviews and price and I'm happy to say I picked right.  I suspected they didn't come with the little screw for the bracket and they don't so you'll need to expect to re-use that from your old bracket. They are perfect replacements.
