Chrysler Corp. is consolidating its Chrysler-Plymouth and Jeep-Eagle marketing divisions. Martin Levine, Dodge Division general manager, becomes general manager at the new combined division. Ray Fisher succeeds Mr. Levin at Dodge Division, from general manager, Chrysler-Plymouth. Eagle General Manager Ed Brust will be appointed to a new, as-yet-undisclosed post. The changes aren't likely to impact Chrysler's agencies. Bozell Worldwide, Southfield, already handles Chrysler-Plymouth and Jeep-Eagle; BBDO Detroit, also Southfield, handles Dodge. More changes are expected, some as soon as this week.
