Simonton Slider - Your part 81-158 looks the same, the measurements are the same, but the wheels we have our 1 1/2" in diameter, the wheels on the replacement part are 1 1/4" in diameter. Will the replacement part work?

Thanks for posting. Yes, the adjustment screw in the back of the assembly will allow you to adjust the wheels to make up a difference in wheel diameter within + or - 1/2", so if that's the only difference, the 81-158 should work for you. Let me know if you have any further questions.
