Thank you.
That solves a mystery I've had for years. I see it on Vin tags and I see it in parts catalogs. My take is when on the top of a Vin tag (DD) it was for the Delivery Date to be stamped by the dealer. Most were not stamped. The paper work was suffice.
When in a parts catalog it means, what Chevy called, a Dubl Duti. Package Delivery style truck and etc.
Thanks again.
