Struggling General Motors Corp. is discussing the sale of its 7.9 percent stake in truck maker Isuzu Motors Ltd. to Mitsubishi Corp. and Itochu Corp., the two trading houses said Thursday.

GM, the world's largest automaker, is in dire financial straits and is trying to raise funds to turn itself around.

Both Mitsubishi and Itochu officials said they are seriously considering purchasing GM's Isuzu shares, but have not reached a decision.
