Woodruff key is a special part (Ford steering part number, not a hardware number), not a standard key, with a slightly shallower lower part than normal. This is important if using the stock headlight and horn rod, which will not like what happens with wrong one. A standard one just needs a little grinding at bottom curve to work.
