Keep in mind, those of you with LSD now can't use a lockright without changing to an open carrier.

I hope they do make one. The spline count has nothing to do with whether they will work or not, as there's no part of a lockright that comes into contact with the axle shafts. I guess it just needs to be a 4 spider rear....later 33 spline axles apparently have a 2 spider rear.
