I no longer have the part# but you can get it from GE after wading through some of their menus. They will e-mail you the parts breakdown, and you want the jam nut that the jackscrew rides in. It is enclosed in a little sheetmetal container. I shopped the part around, and eventually paid about $28 for it. I think GE wanted approx $50 and so did another local shitbag parts supplier. I hope this helps.
