I have added a pin where the business is located. The buildings number is 1817, with 2 companies sharing the building 50/50 (The Rim Plug controlling the northern half, and Junior's Auto Service controlling the southern portion.) 

Using street view, the very 1st dock where the pin is located contains the company number written on the door, stating "Deliveries please call 708-776-3119." Just south down the street, at the very end dock, a logo displaying Junior's Auto Service is seen, being completely unrelated.
