We have a "Sears Service Center" locally. You walk in with the model # of your appliance, toolbox, lawnmower, whatever ... and they have on the computer an exploded parts diagram. You point to what you want, they put it into the computer, and the mothership sends it to you in the mail.
Mind you, expect to pay through the nose for sliders. Donno why, some parts aren't bad, but those... ow.
Alternately you can call 1-800-4-MY-HOME and press buttons to get Parts, and then talk to someone who won't know what you want cuz *they're* looking at the parts diagram and not you.
NB: I have no association with Sears, Roebuck, K-Mart, Orchard Supply, Martha Stewart, Mario Andretti, or the gray aliens putting stuff up your butt, save that I've bought a certain amount of Sears products over the years and have learned how to get parts and service for them.
