I removed the bottom cover plate from the washer to disconnect the power line at the connector box to gain enough slack to pull the unit out from under the counter far enough to access the rack mounting screws located on the outsides of the tub. Removed two wood screws securing the top of the dishwasher to the underside of the counter lip. After sliding out the washer far enough, I made cuts in the insulation since the screw heads (5/16" hex socket) that secure the tracks are under the insulation, which I later taped back together after installing both tracks. After much time, removed the right adjuster from the rack (an overly complicated contraption) and replaced it. Installed the rack on the new tracks and broke the same tab on the new adjuster when I tapped down lightly on the rack, forgetting the tab needed to be depressed to let the rack fall into place. Not wanting to buy and install yet another adjuster, I used a tie wrap around the remaining section of the broken tab and the rack to secure the rack to the adjuster. Maybe good for another few years.
