Looks like there may or may not have been a strike in 1964. Walter Reuther who started the strike at GM in 1946 Persuaded President Johnson to start what was called a chicken tax that slowed the importation of volkswagen vans that where classified as light trucks so they may have not had a strike. Below is the quote I got the information from. I hope this helps.

"Walter Reuther played a role in a historic episode during the early 1960's, known as the Chicken War. France and West Germany had placed tariffs on imports of U.S. chicken. Diplomacy failedand in January 1964, two months after taking office, President Johnson imposed a 25% tax (almost 10 times the average U.S. tariff) on potato starch, dextrin, brandy, and light trucks. Officially, the tax targeted items imported from Europe as approximating the value of lost American chicken sales to Europe.
In retrospect, audio tapes from the Johnson White House, revealed a quid pro quo unrelated to chicken. In January 1964, President Johnson attempted to persuade Reuther not to initiate a strike just prior to the 1964 election and to support the president's civil rights platform. Reuther in turn wanted Johnson to respond to Volkswagen's increased shipments to the United States;

The Chicken Tax directly curtailed importation of German-built Volkswagen Type 2 vans in configurations that qualified them as light trucks — that is, commercial vans and pickups. In 1964 U.S. imports of "automobile trucks" from West Germany declined to a value of $5.7 million—about one-third the value imported in the previous year. Soon after, Volkswagen cargo vans and pickup trucks, the intended targets, "practically disappeared from the U.S. market." As of today, the Chicken tax remains in effect."
