Distribution and Auto Service (DAS) in the United States was the company that prepped all new Datsuns when they came off the ships. Originally it was an independent company, but later was purchased by Nissan USA.
If you're in the USA, chances are DAS prepped your Datsun 1200 before it went to the dealer. Their main office was at the Port of Los Angeles.
DAS is still in business. Having grown from one site in Long Beach, CA to eight sites nationwide. The Seattle location closed in 2002.
