Chrysler, Studebaker, and Packard used Autolite equipment along with some others. Ford didn't get involved with part of Autolite till 1961 but they were forced to sell their interest in it by the early 70s to Bendix Corporation. The starter and generator part later became Prestolite. We used Prestolite starters and alternators on the aircraft for years and still use a version of the alternators but they are now made by Hartzell Engine Technologies.
