Assuming your wheels are convex, either of these could work. The difference between them is that the 23-225 has ball bearing wheels. As for removing the old roller, you'll need to first remove the door and place it on a stable surface. Then, get a pair of needle nose pliers and gently, but firmly, wriggle the hooks out of the slots where they're installed.
