Look at the 84-074 roller. I believe this is the one you are looking for. Check to see if it matches up to yours, as far as size goes. We also have it in stainless steel, the 84-074B.

Thank you! So happy to have found them. Do I just order that part number from this site? Also I will need the screws that adjust the rollers...do you have part numbers for them or do they come with the rollers and are just not shown?

Great, glad to hear it matches. You can purchase directly from our site, yes. The 84-074 does come with screws that measure 8-32 x 5/8". You can see more information in the product description on the 84-074 store page. Thank you for considering us!
