Hello,
We'd be happy to help but we would also like to see the front of the roller where the installation screw installs. That will help us narrow down your options. Thank you!
The 81-263 looks similar to your roller but the housing is thicker at 5/8". The 81-090 roller is thinner at 1/2" but it's open at the top of the housing with no place to install a screw to secure it to your door. Take a look and see if you could carefully widen your door frame to accept the 81-263. Another idea would be to replace the wheel with the 81-223. You might be able to reuse your same axle but we do carry an axle kit, the 81-310. Take a look at the suggested hardware and related videos to determine the best option for your repair.
We're happy to help. Just let us know if you have any other questions or concerns.
