In the above photo. A := Zero, C:= LA. The Zero does indeed have the two float adjustment screws but the LA covers also have room for them.. The difference is really so minimal that it hardly would make sense to use multiple moulds.. especially without functional improvement since the design needs to be sufficient for the Zero and since the screws can adjustments on can't use them as part of the retention..

It looks like the Zero cleats have longer adjustment screws, so probably need more of a cut out on the cleat cover.
