M/W and Strange splines are the same on 40 spline. M/W are a different pitch on 35 spline and will not interchange with Strange. The M/W 40 spline spools I own all have the splines cut all the way to the end of the spool. The Strange are recessed up inside the spool and require axles that are full length and end in the proper position to get a full spline engagement.
