My Lazy Boy recliner has an adjustable height on the foot rest. It still works but only in the lowest position. A small metal piece (about 1/2 in wide by 1 1/2 in long) was laying below the chair one day and now when I put the footrest up where I want it, it doesn't hold for more than a minute or two. Any idea where this came off of and what is it called? I can probably fix it myself if I know what and where....
