yes, but we have spent the last couple posts discussing how there needs to be a 5" diameter roll plate on top of the bottom mount and below the bag, the hockey puck spacer goes between the mount and the roll plate. if your mount setup does not have the separate roll plate then you will need to install one.
I dont have a lot of pictures of the bag installed, here is one of the lower mount, you can barely see it just in front of the lower shock mount, you can see it is only about 2x2 without the roll plate installed.
here is the only picture I found of the bag installed and squished
