At least for drum brakes, all the 1T stuff is bigger. I'd expect the same for the disc brake parts, but I have no experience with it. Maybe if you keep looking at parts stores, you will eventually find a counterman who knows his stuff. I had to visit the local NAPA several times until I finally got my 3/4T rear brake adjuster components. Some were boxed wrong Chineseum was most of the problem.
