Using these new tracks (LH was good, but replaced just in case), I repaired the unit in no time. Ridiculously easy. 'Hardest part was screwing in the bottom sheet metal covers that cover the underside of the unit. I did need to view the video re: replacing the upper rack height adjuster to seek exactly where the rack attaches to the slides (thanks for that video). APP has always had good prices and great instructional vids.
