I'm having trouble finding this exact roller. Do you think the 81-027 could work on your door as a substitute? Looking at your photo it appears that you install the mounting screw up into the roller and then into the the bottom of the door. You can install the 81-027 the same way, accessing the the hole at the top of the roller housing. Take a look and see what you think. I know the height appears to be 1/4" less, but that might not matter because of the way the roller is mounted into the door. Check the width and compare it to yours.
