TRIVIA: What was the Blues Brothers' license plate number?:  Illinois BDR 529; Registered address 1060 West Addison.  Do the numbers have any significance?  The letters & numbers in the license plate refer to a bike club in Dan Aykroyd's home turf of Toronto, the "Black Diamond Riders".  The clubhouse was located at that city's 529 Jarvis Street
