On your other post looking to identify a broken white piece, I posted a link to a parts supplier. Look there to see if you can still buy the part. Try lots of parts houses. Some will have stock, when others don't. Ebay, too. If not, and you still have all of the pieces of the lever... and you have a friend with a 3D printer... Or a "Makers" group nearby... Maybe you can get it printed. HTH.
