Please refer to the photo(s) submitted - I believe I have the No. 20810 left hand crank, offset (4-7/16") down. This part has failed and I am looking to replace it. Thanks!

Thanks for posting. Have you seen our 39-031 & 39-032? These looks pretty close to what you have, but compare them and see what you think.
