Need 81-248 with a grooved roller wheel

A handy person from Houston says:
I have a roller that is exactly the size of your 81-248. EXCEPT I need the grooved roller wheel not the flat wheel. I have spend hours and hours looking and your part 81-248 is exact same dimensions and the only company on the planet that shows the exact same part I have. Any help with finding this exact assembly but with the correct plastic wheel?

Take a look at our 81-247 replacement roller. The 81-247 is the same style roller as the 81-248 it has a concave wheel.
