OK now I am be wrong with this but I was looking at 4x4 parts and i see that they have a detriot locker, for a h233b with 31 spline and I believe that this is what I have in my truck but i could be wrong. If I had the LSD and just put in an open diff carrier, could I put this locker in? I may be able to get my hands on a non lsd carrier for nothing, so that is the reason that I ask. Thanks.

Nope, it's 31-spline only, and you're 33-spline. Unlike the Powertrax Lockright which keeps the original side gears and could conceivably be used in 33-spline diffs (since the splines are in the side gears, shouldn't matter, but there are other differences that prevent it), the Detroit replaces the side gears and is absolutely 31-spline, period.
