DETROIT AP – General Motors Corp. is in talks with its former parts arm Delphi Corp. about taking back some Delphi factories that make key parts for GM vehicles, a person familiar with the negotiations said Monday.

Troy, Mich.-based Delphi has been operating under Chapter 11 bankruptcy protection for more than three years, and like many suppliers is struggling with the shrinking U.S. auto market. The person said GM is worried that the plants could shut down if Delphi runs short of cash, crippling GM’s production.
