Product review (5 stars): This part will work in place of 3550JL1016A
This product will fit into refrigerators that originally used part 3550JL1016A (which has been discontinued).  All the pieces from the old shelf will fit onto this shelf (metal bar, lower clear baffles, glass shelf, rollers).  The old style drawers will fit into this, but with some gap when the drawers are closed.  Ideally the drawers should be replaced with those that go with this updated design, part numbers 3391JJ2012D and 3551JJ2019D.  Unfortunately neither LG nor Sears have this part listed as an option to replace the old style shelf.  This is very unfortunate customer service as there is an available solution for the discontinued part.
