Similar roller, 7/8" wheel diameter.

I recently purchased 4 rollers assemblies from you, however when I received them, the roller is 1 1/4". Product code 84-016
The roller on mine is 7/8" in diameter. Do you carry another size wheel or did mine wear out that
much? The metal piece and spring are exactly the same on both new and old rollers. If the size difference is
due to wear should I replace all of the rollers
on both doors. You're help is greatly appreciated.
