This was really a simple repair. I just kind of pried the shelf retainer bar bottom slot that holds the old endcap on out a little and was able remove the end cap and replace it with the one from 'partselect.com' and reinstalled the end cap - this was a simple repair and I'm glad that they had the part. It was also simple to find on their site.
P.S. This may or may not help; while the refrigerator is a 'Kenmore', I found through researching that it was actually made by G.E. and branded for Kenmore.
