From Wikipedia:
AM General’s roots (and its location in South Bend) lie with the “General Products Division” of Studebaker, which, along with its substantial defense contracts, was acquired by Kaiser Industries after Studebaker left the auto industry in 1966. American Motors Corporation (AMC) became the owner when it purchased the Jeep Corporation from Kaiser in 1970, and Kaiser left the auto business. In 1971, AMC made the General Products Division of Jeep (producing contract and non-commercial vehicles) a wholly owned subsidiary and renamed it AM General Corporation. American Motors ended its history as an independent automaker in 1982 when controlling interest in the company was purchased by France’s Renault. US Government regulations forbade ownership of defense contractors by foreign governments, and Renault was partially owned by the French government. Therefore, in 1983, AM General was sold by AMC to the LTV Corporation and it became a wholly owned subsidiary of the LTV Aerospace and Defense Company.
