I think the 81-154 may work. The width of the 81-154 is 3/4 inch while mine measured 13/16 inch. I could be off. The diameter of the wheels are 1 1/4 inch, same as the 81-154. If they don't fit. can I return them?

Hello,
I agree that the 81-154 looks like a promising replacement option. Keep in mind that we measure the width at the widest point where there is an offset near the center of the roller. Also, you are welcome to review our return policy here. Thank you!
