All one needs is a flat uniform surface that would limit pedal travel without constraining it laterally in any way.
The above picture's clutch stop is clamped to the clutch lever, there's no groove to hit or miss. The stop is bolted to the lever. There is an adjustable bolt/post that comes out of the stop and its length is adjusted so you can find your proper "stop position". It's just like the E46's solution, except that the stop is afixed(bolted) to the clutch lever instead of on the floorboard.
