My last picture shows a close match. The wheel dimension is what concerns me. The wheels I have measure 1/16 bigger than the ones on your catalog. Which I would actually like the wheel to be 1 1/4 O.D. Hope this is more help, hope to hear from you soon.

Thanks for contacting us. After looking over your photos, I think our 81-250 should work. The wheel is not that much smaller, and you can always adjust the roller to make up the difference.
