It looks as though there is an overhang around the lever boss. If there is, dose it with PB Blaster or Plus Gas then carefully tap it off using a long screwdriver as a drift with a hammer, using firm, sharp blows - from behind (the right side of the frame. If that doesn't work, Dremel away carefully - wrap a damp cloth around the frame to protect the paint from hot abrasive wheel debris?
