While the service station is clearly shown on the 1917 map, the following two aren't. However, by comparing the buildings in the background to other pictures, I can safely figure out where the first, the garage, was. To see this, go to this post and look at the buildings marked D and E. The garage can be seen on the right hand side of the third building, the one with the Horn Paint sign on front.
Sorry about the quality of this picture.
