Hello! It's hard to make out based on this picture. Our 87-138 appears similar, though. Look it over and let me know if you could use it as a substitute. If not, could we see more pictures of your part from a few different angles? Thank you!

Thank you. I still think our 87-138 is our best match. I recommend that you carefully compare it to your own roller to confirm.
