Part arrived in three days, excellent service, thank you appliancepartspros. Only issue was getting old shelf out. There are two tabs that didn't seem to release anything. A search of YouTube for help yielded no results. Remembering that Samsung repairmen always have a screwdriver handy, I pressed tabs and pried and the old shelf popped loose. New one settled in and snapped into place. Really as simple as I had hoped it would be.
