Without seeing the roller assembly with dimensions, we can't be sure. Our guess would be either the 81-023 or 81-279, but this is just a guess and I do not know if either will work. Please compare these to your existing rollers or, better yet, remove your rollers from the door and send us photos. That will help us find a better match!
