Was doing an oil pump on my rd1 and misplaced the timing gears woodruff key,no idea what it looks like since I never touched it and it walked away :/ but of my research I can’t find the half moon shaped one that’s supposed to be there,only part number I could find is 90704-634-000 and that’s the harmonic balancer woodruff keys and it’s short and a rectangle. Any help is appreciated
